Date Axis in Charts

I've seen the thread that says Numbers does not support a chart with a date axis. That is, a chart derived from a table that has a date column with dates irregularly spaced in time.
For example, here's a table of visits to a supermarket and the price of Wheaties on each visit:
DATE PRICE
8/12/90 $3.50
8/14/90 $3.60
9/2/92 $4.30
6/4/94 $4.00
Right now, if you turn this into a chart, you get a graph with each data point paced equally apart. Useless. What you want is a chart with an x-axis that's a date range, with each data point plotted at the appropriate point along that range.
I'm surprised that Apple doesn't support this feature. So, two questions.
1. Anyone know if this is in the pipeline for the next version of Numbers? I'm ready to chuck Excel, but this is a show-stopper for me. Can't switch without this feature. Anyone know when the next version is due?
2. Anyone know any reasonable workarounds?
Thanks.

I really don't understand why.
You had a 30 days free trial version giving enough time to see if the app was fitting your needs.
But don't worry, it appears that you are numerous to do that.
To be back to the app itself, it appears that the choices ruling dates are not perfectly consistent.
For some aspects they looks like strings, for others, they look like numbers.
I was acustomed to dates being a number displaid as a dateString.
For instance, if a cell contains 37995 in an AW spreadsheet, when I give it the date format, it is displaid as: 10/01/2008 (I am using a French system).
In Numbers it's not exactly that and I can't get it displaying 37995 as a date.
In fact I knows, but it requires an AppleScript.
If someone found a way to do that with Numbers's functions, I am interested.

Date Axis Line/bar Chart not working properly when rendering through SDK

Hi all,
When i render a existing Crystal report 2011 through java SDK code(Eclipse) bar chart is working fine, But the Date Axis line chart is not displaying properly. the properties are getting changed.. Any clue how to handle this? Do we have particular jar for Chart?
Thanks in Advance!

Hi Mirthu
I moved your post to the SAP Crystal Reports, version for Eclipse SCN Space. Unfortunately, all I know about Java is that it's in the cup in front of me . But I will get someone to have a look that should be able to help you ASAP.

Is coloring the individual points possible in Numeric Axis-- Date Axis line

Hi,
I have a requirement to be able to chart with specific points in the "Numeric Axis-->Date Axis line Chart", in a different color, I can do that easily in "_XY Scatter_" chart with "Color Highlight Tab" in CR XI.
Any idea if the same functionality is possible/available for "Numeric Axis-->Date Axis line Chart" chart, it lets me define the rule to define color based on the Table.value, but doesn't show in that color even when the data has met the definition (ex:Profit=100k).
Thanks for the help.
Krishna Hegde

The Color Highlight works fine. Did you try with some other options you have in 'Color Higlight' maybe like 'Greater Than' or Less Than...just to test it.....

Date axis and trendlines

Post Author: srmalloy
CA Forum: Charts and Graphs
I have a report that shows a number of aggregated data values with drill-down, with subreports that display month-by-month data at that drill-down level that include line charts showing several of the values, each of which has a trendline. The problem is that the horizontal axis displays the month values as 'monthnumber/year', i.e., '10/2006'. I can force the axis labels into a more readable format by going into Chart Options to the Axes tab and selecting 'Show Time Scale' under 'Show Group Axes', then clicking on one of the axis labels, selecting 'Format Axis Labels', and picking the 'Feb-02' format. I can also do this by going to the Chart Expert, selecting Numeric Axis as the type with 'Date axis line chart' as the subtype, then doing the same 'Format Axis Labels' change.The problem is that, when I do this, the trendlines become brain-dead, turning into a horizontal line across the chart well away from the actual data line. Is there some way to get the data axis labels to show in the 'mmm-yy' format while still having trendlines function properly? The main report has a dynamic parameter to allow the viewer to select which fiscal year of data they want to view, so hard-coding the axis labels as specific strings is not a viable option.

I'm sorry. Perhaps I wasn't clear. I am interested in having a graph that looks like yours (numbers on Y and dates on X), but I want to display the equation (y= Ax+B) of the trendline. R^2 seems to work fine with an axis with date values, but if I try to display the equation I get the text "Equation couldn't be calculated because one or both axes have data values." on my graph instead of the equation. KOENIG Yvan's solution is helpful in that it allows me to have an equation, but as far as I can see, I lose my date axis (X just becomes 1, 2, 3,... instead of 1/1, 1/2, 1/3...). I am hoping there is a more elegant solution than placing the two graphs on top of one another.
Also, is there a way to find the trendline for only a few points of a series without making a new series of those few points?
Thank you!

Charts data axis scaling problem

Post Author: rameshp
CA Forum: Charts and Graphs
Hi ,
I work on crystal reports XI.
I'm facing problem regarding scaling data axis. I have illustrated that in the following lines:
case1) if i have high values (sum of bytes) like more than 600 etc. its scaling data axis from 0 to say 1000.
case 2) if i have low values like 0,1 (bytes) then its scaling from -4 to say 6 .
I don't want negative values on data axis . I want from 0 to max. So what's the better way to do this using chart expert.
Your suggestion is highly appreciated !
Thanks,
Ramesh.

satwar,
There is no "trick", we're just victims of the limitation that WebI has in portraying XYZ type charts to our better liking. I submitted a request to Business Objects Tech Support in Oct 2006 and became the proud holder of two ADAPTs:
ADAPT00676587 u2013 for the scaling issueADAPT00676609 u2013 for the stacked bar chart, line graph issue
When fully implemented, the scaling for Y and Z should be able to correspond to each other. For instance, max value of Y and max value of Z will set on both scales the same max value. I don't discourage you from submitting a trouble-ticket, perhaps if they get more noise on this situation they'll resolve my (our) ADPAT sooner, but just hoping....

Can we print an array of dates on the chart X-Axis?

Hi,
I have a requirement in which I have to print all the dates in the selected date range on the chart axis even though I donu2019t have the data for all the dates in my DB.I did not find any direct solution in Crystal Report Designer (2008, XI) except we can use "time scale" option in axes tab of chart option but this option also does not provide the required behavior completely.
After implementing this option I get the date range on chart but from the date I have data in the DB and to the date I have the data in the DB.
For Example, though I have selected the date range from 2nd April to 8th April, dates in the chart are starting from 5th April since I have the data in the DB of 5th April and 8th April.
To overcome this limitation of crystal report I thought of creating an array of dates of the selected date range. I can create the array of dates in crystal report but donu2019t know how to use this array in chart to show the summary data.
I also want to base my Group on this array since I want to show all the dates in group even with count zero.
Thanks & Regards,
Amrita

Hi Sourashree,
I am using the following formula to create an array of dates.
numbervar dateDiff:={?eDate}-{?bDate};
dateTimeVar array dateArray;
numbervar i;
for i :=1 to 7 do
    redim preserve dateArray<i>;
if(i=1) then
    dateArray<i>:={?bDate}
else
    dateArray<i>:={?bDate}+i;
This formula is a print time formula since when I specify "WhileReadingRecords" array remains blank (I have confirmed this by returning any single value from the array).
I can not base my Group and Chart on any Print Time formula since these two get calculates at read time.
Can you please let me know if there is any other way of creating the array at read time? Or should I create the array in main report and then pass it to sub report?
Regards,
Amrita

SSAS2008 r2 and Excel Line Chart and Date Axis

Hi
Excel 2010. SSAS 2008 R2
I have a excel line chart made out from SSAS pivot table with a date dimension (date) and No of licences.
Currently, it displays 1/Jun/2014 to 30/Jun/2015 (FY2015) and this looks really ugly.
While keeping the details, I'd like to display by Month-Year.
However, while I can do this with other normal excel data, I just can not do it with SSAS Pivot table.
Under Axis options, I ticked 'Date axis' but it won't bring up date options.
I think I tried everything but just can not figure it out. I wonder if it is even possible.
Th date dimension is recognised as date because I can apply date filter. I want to make it neat. Can anyone help me with this please?
It must be 'Date' Level.
Kind regards

Hi SQLMa,
Could you please elaborate more detail regarding the "Date" dimension structure? In order to display the date format with Month-Year, we should build a hierarchy to organize the granularity of date dimension at SSAS level. Please
refer to the documents below:

CR in VS2005: Line Chart Date Axis

I believe this is posted in correct place:
I have line chart that is displaying daily data. I want to display a month worth of data with each day's data point plotted.
The X axis is a system.datetime of the day for the data (actually group label); I have formatted this to mm/dd/yyyy in the format editor. My graph X axis labels are overwritting each other and I can not see how to 'scale' x axis labels to prevent this.
In reviewing similar existing posts I see reference to options that do not appear to be available in Net VS2005 (recently updated CR and VS).
Is this limitation of VS version of CR or am I doing something wrong ?
Thank You, fd

Thank You for your reply. I belive that I may still be limited by version in visual studio 2005 (CR updated to 10.2.3600).
When I right click on any object in graph I am presented with list 'Format Object' (border of chart, keep object togeather, etc), 'Chart Expert' (very limited selections: show grid, title text, etc) and 'Chart Options' (again very limited selections: Template,General,Titles,Grid). In the grid section chart options there is indeed a "data axis", "numbers" formatting section that allows for formatting as date but not any alignment etc.
I am not adverse to purchasing an added CR designer but would like to clearly understand advantages. It is also of concern that this "date" x axis should be treated as an x-y plot rather than the dates being used simply as labels.

Date Axis Stacked Area Charts

Hi,
I'm just evaluating the full version of Crystal Reports 2008 having had some frustrations with the design restrictions in the basic version that ships with Visual Studio 2008. Particularly important to me is the design features for charting data. A lot of the charts I need to build have daily data points and the dates for these data points are represented as labels on the X axis. My problem has been that when you try and build a report with several months or more worth of data points the X axis is getting way too crowded even to the extent of being unreadable with overlapping labels. I've noticed in the full version that there is a date axis chart type whereby you can alter the scale of the X axis e.g. to only show a date at a frequency once per month or greater resulting in the X axis being readable. This seems to work great for line charts etc, however one of the charts I need is a stacked area chart and unfortunately I can find no options / chart types that allow me to scale the dates on the X axis. I've seen there is a date axis chart for area charts, but there is no option of having this chart type as stacked. I know you can also skip data labels in X axis group options, but the max I can skip is 2 and so that doesn't really help me either.
Is there any way of achieving a stacked area chart with a scaled date axis in Crystal Reports 2008? If not it seems to me that the lack of this feature is a real omission from the product. Even Excel charts can handle this type of chart and I would imagine Crystal Reports charts should be more advanced in its charting capabilities.
Any help or recommendations would be appreciated.
Kind Regards,
Mark

I have run in to the same problem. I work for a systems integration company and I purchased this software because I have a lot of crystal reports and .NET experience but I have very minimal crystal chart experience. I need to use the charting to display data over time collections. I need to show all data points collected but for some series that I deal with I need to be able to scale the x-axis labels to something that is legible. There is an aftermarket package(CRReports3.5) for $500 more dollars that would enable me to control this but it seems like alot more money for a small piece of functionality that should already be built in. I have Crystal Reports 2008 and am working with visual studio 2008 can someone please tell me is there ANY WAY to achieve this functionality without purchasing additional software? Otherwise this software purchase was worthless for my current project.

Display Data on waveform chart or XY graph over a long period of time

Display Data on waveform chart or XY graph over a long period of time
Can anyone help?
I am acquiring data from an Ni DAQ card with the following parameters - sample rate = 12800, number of samples = 4096. I want to extract order information so as to track changes in the amplitudes of certain frequency harmonics. So I use the sound and vibration toolkit to extract this information as shown in the attached Vi. I will like to plot the resulting amplitudes against real-time starting at the time the Vi was run. I really want the display to show these changes over long periods (eg. days, months and even years).
Problem.
I have tried to plot the Y component of the resulting magnitude for a given order on a waveform chart. My choice of the waveform chart is because I also want to display alarm limits (using the mask and limit vi) (I can't have these lines displayed on an XY graph plot). I tried adjusting the scale offset using the property node and setting the offset to current time. However, the display on the X-axis can only show a span of 2 minutes as will be seen when you run the attached vi. I want the time display on the x-axis to be over a period of days, months and even years. Is there a way to set the maximum scale on the x-axis to be say a year or so in future.
I really want the display to be like the one in in the second attachment.
Attached is a sample VI created using an Ni USB 9234 DAQ card. Any card will do but I am only getting the signal from one channel for this example
I will appreciate any help that can be given to me.
Thanks

Long term testing can be tricky- and we'l get into that later. Lets start with the basics that you have wrong.
The vi as you have constructed it has only one memory element, the chart history length (default is 1024.)
You can change the number of points the Chart will remember by Right-clicking the chart an select Chart History Length from the menu.
But for a long term test - and one where you want to REMEMBER the first value you need a memeory element that is independant of the application. Your PC WILL loose power or need to be rebooted eventually. Heck it might even need to be replaced! you really need to store your data in a file. Preferablly in a file that is backed-up on a regular basis so you don't lose every point of data if the PC dies. It realy hurts when you have to restart a 2yr test because you've lost the 18months of data you collected.
For an application like this I would seperate my "collection" and "Evaluation" operations.
Have one vi that takes the reading and writes it to a file at a configurable rate You may want 1reading per minute for seveal days then 1 per hour for a few weeks- then maybe only once or twice a week for the next couple of years since you are looking for LONG TERM stability. having too much data to evaluate can take a lot of digging to find the few things that interest you (but always take more that you think you need)
Have another utility that COPIES the files, reads them and displays the data you are interested in that day. The data you want to look at won't change over time HOWEVER, you WILL want to analize it in different ways depending on what the data trends look like. Having seperate routines for collection and display allows you to update the display style and analisys without even stopping the collection vi (much less editing the vi)

How to auto change the name in X-Axis and Y-Axis in chart ?

Hi, I want to plot data into a chart. I make a selection switch for each channel, there are for temperature measurement and voltage measurement.
What I want is when I switch the selection to temperature measurement, the Y-axis´s name change into Temperature and when it is voltage change into Voltage.
Can LabView do that ?

How to extract the data from the chart. Data were not saved

Hi everyone. Beginners question, but could not find an answer to it
How can I get the numerical data from the chart. Chart is already on the screen and data vere not saved into file during VI run. All I have - just chart, but I need numbers
Thanks
Message Edited by olka on 07-18-2007 09:41 AM

You can still do it, the process just changes a bit...
Copy the control to a new VI as before, and change it into a control.
Create the diagram shown in the attached screen shot.
Run the new VI. You will get two arrays: one of x-axis values and one of y-axis values.

Dates in Flash Chart Bolded

I have a really frustrating issue with the formatting of my Flash charts. Whenever there is a date on an axis label it will bold all dates along the axis. It also seems to forget the formatting I want for the rest of the chart.
I have all of my charts to show the axis in 10pt Arial. Things work fine if there are no dates. The minute a date goes in the date axis is bold and the other axis is back to the default font and size. Any ideas?

Maybe this issue is a bug. I changed the rotation back to 0 and the text shows normal. Although, if this was going to happen I would have expected the same behavior with standard text.

Date Formatting in Charts and Dynamic column resizing in Cross tabs

Hi All,
I am new to Design Studio, so am in desperate need of your help on the following:
Is there a way we can change the date format in x axis in charts?
For ex: Am getting dates as mm/yyyyy from BW but requirement is to show in yy-Mon
Requirement is to display data in cross tab just below the charts. How can I make the column widths in the cross tab the same as x-axis divisions in the chart? Also, this will be dynamic as depending on filter selection x axis scaling in charts will vary.
In cross tab, can I hide the column header?
Would really appreciate any kind of help from you.
Thanks & Regards
Swasti

HI Swasti,
To answer your first question, in Design Studio it's what you see is what you get! so it shows the Data Labels as it is in the BEx output, if you have to modify this you have to change it in the Background.
There might be CSS workarounds, but I am not sure if that will satisfy your requirements.
You can fix the Column width, but it would be constant, aligning that to your X-axis would require a lot of Effort.
You cannot hide the Column header directly, but one workaround would be to use a white BG text component to overlay on the Crosstab.

Data Format on charts

Is possible to get Decimal Places UP to x on chart properties data format?
I can change this property on criteria column, but If I want to change Vertical Axis Labels, Data Labels...only can change decimal places from 1 to 6...but I would like to select UP to 2.
Changing xml advanced code with minDigits=2 to minDigits=0 and maxDigits=2...doesn't work.

In a pie chart, the whole 'pie' represents 'all of the data graphed'.
In percent, that's "one hundred per cent", or "one hundred per hundred"
As a fraction, the whole circle represents 100/100, or 1/1 or 1.00 — all of which mean "one whole thing".
Smaller portions are written as fractions of the whole, with the 'whole' fixed at 100 (percent) or 1.00.
So a 20 pence piece represents 20/100 of a pound, which is 20 percent of a pound, or may be written as a decimal as 0.20 pound.
One pound is 1.00 pound, or 100% of a pound.
A 10 pound note is 10.00 pounds, or 1000% of a pound.
And getting into the range of values on your Chart 16, 455 pounds is 455.00 pounds, or 45500% of one pound, which, as you can see, is correctly represented on the chart.
Here's a pair of charts, and the table that feeds them. Same data as in your example, but with the Y axis scale showing the raw data numbers on Chart 1, and the fraction of the total (1146) that each amount represents on the chart 2.
Formatting the Y axis labels to show percent doesnt change the values. The numbers are multiplied by 100, and the % sign is attached to show that these are the number per hundred. For chart 1, where the current scale takes no account of the total, converting to percent doesn't make sense.
For Chart 2, with the current scale, the four bars show (approximately) 0.2, 0.3, 0,4 and 0.1. Altogether, that's 0.2+0.3+0.4+0.1 = 1.0
Converting Chart 2's Y axis values to percents changes the labels on the four non-zero lines to 10, 20, 30 and 40%. The four bars now show 20, 30, 40 and 10 percent. Add those up and you get 100% (which is always the total percentage of 'the whole thing'.
