X axis scale

I know this is a basic question but I am unable to figure it out. I
want to scale the x axis of a plot. I am using plot waveform and
printing out the spectrum of a signal. I wish to change the x axis from
cycles per second to cycles per minute but am unable to find a
solution. I have tried changeing the x increment property in the
PlotWaveform function call but this does not work. Am I correct with
the x axis increment property and just missing something or is there
another way of doing this.

I found my problem which was the value being passed to the x increment
parameter was not a double thus not changing the scale factor. Which makes
me want to ask another question (which I have also posted)
Is the a function prototype in cvi code which would generate an error/
warning that my parameters do not match those of the function prototype. I
am using MSVC 6 for development.

Axis scale for scatter plots

I'm trying to create a specialized scatter plot, which functions similar to Excel's scatter plot. I'm having problems determining what the min and max values should be for the axes. I would like the program to determine from the input data what the initial min and max values should be on the x- and y-axis, the user can adjust later.
So, I don't want the program to just look at the maximum value imported and round up. For instance, data = {523.7, 514.4, 271.8, 128.5}. The max value is 523.7, round up to 524. Instead, I would like to program to make 600 the largest value on the axis, because that makes it nice round number for the user to view the dataset.
Then, I thought it really depends on the range of the data. For instance, data = {523.4, 523.8, 523.2, 522.8, 523.9}. Here, the range is very small, so it doesn't make sense to have 600 the largest value on the scale. The largest value should be 524 or 525, and the small value on the axis scale should be 521 or 522.
Has anyone else ever worked with this problem, or have a good solution? I would really appreciate it, I've spend way too many days working on this.
Thank you,
Joe

This is off the top of my head and based on a slight variation of your data.
data: 52.34, 52.38, 52.32, 52.28, 52.39
min=52.28 max=52.39 range=0.11
Looking at the range we see it is "on the order of" 0.1. Ie, it is closer to the next lower power of 10 (0.1) than it is to the next higher one (1.0). So we round min down to the next lowest multiple of 0.1 (52.2) and round max up (52.4). 52.2 and 52.4 can serve as the nice numbers.
The range is just a little bigger than a power of 10, so it might be a good idea to check what happens when it's a little less.
data: 135 226 141 143 etc
min=135 max=226 range=91
range is on the order of 100, and the nice numbers are 100 and 300.
As a variation on this strategy if we always find the power of 10 below the range (10 in the second example) we get a tighter fit but the numbers are slightly less nice - 130 and 220.
(I'm pretty sure I've seen - and used! - some java software from the Internet somewhere to find the best scale for axes, so it might pay to look around)
Had to edit my second example and, while I was waiting, found what I have used for this sort of thing: http://geosoft.no/software/index.html (The NiceNumbers class - it finds numbers along a range suitable for major and minor "ticks" but, if memory serves me correctly it extends the range so that the ends are nice too.)

Distributed System Manager trend y-axis scale

I've been trying to monitor some boolean shared variables in the Distributed System Manager. I've been looking at the trend, but I can't find a way to change the y-axis scale from 0-100. With that scale, I can't see if a value switches from 0 to 1. Is there a way to change the scale?
Thanks!

Nevermind, I see that it auto-scales now, the one that I was looking at, I was expecting to change, but it wasn't...

When I upload large streams of high frequency data the x axis scales incorrectly

I have data at 5 kHz for 20 seconds. when I upload this data into the report tab the x axis scales incorrectly and cuts off either the head or tail of the data. The x axis always rounds to the nearest second while i need it to start with the data. Any ideas?

Hi wpruitt3,
Take a look at this knowledge base article.

AnyChart DateTime axis scale

I'm trying to display the x-axis for a chart with a "fixed" scale of months within a given period, using a Line Series chart.
My query is like
select null link,
to_char(sample_date, 'DD/MM/YYYY') label,
water_temp value
from my_table
I've followed the documentation here: http://www.anychart.com/products/anychart/docs/users-guide/DateTime-Axes.html
Sadly the markup in this guide vs the source displayed is different..ie, when you go to open the first bar chart there, the xml that is showed on the pop-up doesn't match the code in the main section, and it's missing the min/max values.
I've set up the <locale> tag as follows:
<locale>
           <date_time_format>
             <format><![CDATA[%MM/%dd/%yyyy]]></format>
           </date_time_format>
      </locale>I've modified the x-axis <scale> tag
<x_axis>
            <scale type="DateTime" major_interval_unit="Month" minimum="01/01/1999" maximum="06/01/2012"/>
</x_axis>But I can't seem to get the chart to pick up the min's and max. From what I can get from the docs, I should be able to set the scale up on the x-axis somewhat independently from the actual data points themselves.
Is this supported and has anyone done this successfully?
Thanks in advance.

Hi Folks
I'd like to ask if anyone has managed to get an AnyChart gauge working with date & time based axes and data values.
My development colleagues have scoured the documentation and tried several times to get this to work without any success.
The AnyChart documentation suggest that date & time based axes and data values can be used with certain chart types but is then vague about their use with the Gauge chart type.
Any tips on how to make this work would be very welcome - and if it's simply not possible, we'd like to stop chasing this particular rainbow ;-)
Many thanks
Andy

Apex Chart - Y Axis Scale customization

Hi all,
For a chart in Apex, is it possible to have the Y-Axis scale customized? (Let's say to present all values form 2 and 2 units for instance).
Thank you,
Ana-Maria

Hi Prashant Khadatkar,
As per my understanding, you created a line chart, you added JobStartTime and JobEndTime to values area, and added JobStartDate to category groups. You want to display data of y axis from PM to AM. In order to improve the efficiency of troubleshooting, I
need to ask several questions:
What’s the data type of JobStartTime and JobEndTime?
Is the data stored in database the same as you provided?
What’s the state of report now? Please provide some more detailed information of the report. I would be appreciated it if you could provide sample data and screenshot of the report.
This may be a lot of information to ask for at one time. However, by collecting this information now, it will help us move more quickly toward a solution.

How to change the Y-axis scale for 100% stacked column to percentage ?

Hi,
I add a 100% stacked column chart to a report in Crystal Report for Enterprise. As default, the Y-axis scale shows value from 0 to 1 and the data labels display absoluted data value. Now I want the Y-axis scale to show value from 0% to 100% and the data labels to display percentage value.
Please tell me which option of the chart to adjust ?
Thanks
Mau Vu Huu
The default is like screenshot below:
I want it to display as screenshot below:
thanks
Mau Vu Huu

Looks like a bug in CR for Enterprise.
The same chart shows a scale from 0% to 100% in the CR 2011 designer whereas CR for Enterprise seems to show a number range from 0 to 1.
Here's a workaround:
1) Insert a Crosstab. 'Column' should be the field you wish to show on the 'X-axis'. 'Row' should be the field that you wish to stack up on the bars. Summary should be the measure field
2) Next, right-click one of the summary cells on the Crosstab > Select Format Total > Total > Check 'Show as Percentage of' > Grand Total > Row
3) Right-click the Crosstab > Select Create Chart from Crosstab Data
4) Suppress the section that holds the Crosstab
5) Right-click the chart > Edit Chart Type > Choose 'Stacked Column'
6) Highlight one of the numbers of the Y-axis > Select Format Total (Y) axis > Format > Currency > Choose 'Fixed' under 'Symbol Format' > Replace '$' under Symbol to '%' > Change Symbol Position to '-123$'.

Y Axis scale issue

Hi there,
I've a dynamically driven (through XML) column chart. everything works just fine except the Y axis scale. depending on the data it changes the divisions and some times it looks very odd.
I tried with Auto (Y) axis option then tried giving manual values by determining the MIN and MAX values through XL formulas, but no luck.
Also tried setting the number of divisions to say 6 - unfortunately, it doesn't seem be listening to any of these settings.
Is there any other better way to control this?
please advice
Malik

How to display a fixed min and open max Y axis scale on obiee 11g

Hi,
I am stuck with an issue.
Obiee by default is plotting my bar chart with Y axis scale from -50 to 850 with and interval of 100.
In the graph non of the value is negative of below zero. The graph too plots all the points above 0, even then it starts the Y scale from -50, not sure why?
I wanted to know whether we can by anyway limit the y axis scale with lower limit to 0 and still keep the upper limit open or undefined.
Please let me know if any of you have come across such scenarios?
Thanks

Not being that familiar with the typical labeling on log(log) plots, you
may be able to do this using two scales. Make a graph that contains two
scales. One will be plotted against, the other will be just for labeling.
You can now transform your diagram data, which will change how the mapped
scale is labeled, but the other scale can show whatever you like in linear
or log form.
In otherwords, on the diagram, perform log10 on your data, then display on
a log scale that is hidden. Make another scale vi
sible with linear or log
data. Or perform log10(log10) on your data, display on a hidden linear
scale.
I'm not sure how well this will work. If it is insufficient, you can submit
a feature request on the web site.

How to put percentage sign on the Y-axis scale

Hi all,
I want to draw a column chart to show the percentage share. And I want my Y-axis scale has '%' ended, like "10%, 20%, 30%..up to 100%". In my test, it seems that only numerical text can be shown on the Y-axis scale.
Are there any ways to implement what I want?
Thanks & regards,
Dicky

I just saw that this message is posted in the SAP NetWeaver Visual Composer area. VC does not use IGS charts. If you would use IGS charts my answer would be:
Hi Dicky,
in the Chart Designer go to the Value Axis Line properties and set the Format to "00 %". This should show what you are expecting.
Best regards
Matthias

Force Y-Axis scale to be whole numbers

Does anyone know how to force the y-axis scale of a bar chart to be use whole numbers when you are doing automatic ranging? I am using a bar chart to show counts by categories. I know you can do this if the range is static, but I don't know for sure what the maximum counts are going to be, so I need automatic ranging. When we have values of say 10 or more for each category, the chart looks reasonable, but if we only have a values of 2 or 3 for the categories, the chart y-axis might have a scale of .4, .8, 1.2, 1.6 etc. This looks goofy when we are graphing counts, which can only be whole numbers. Can I force automatic ranging to use integers? I am using Crystal 2008.
Thanks for any help you can give me.

If all else fails, this is a feature in our CRChart add-on library for Crystal Reports.
Macro @SCALE_INTERVAL would do exactly what you want. It's a new feature in the soon-to-be-released version 3.6 however, so you'll need to contact us directly to get an advance copy of the 30day free demo of 3.6 (3.52 is version on our website).

Combo chart- left right y-axis scale are not the same scale

http://img20.imageshack.us/img20/6264/questionk.png
the left and right axis scale are not the same.
how to set it?
Thank you very much!

Hi,
Try this
In Chart, Goto Advanced properties -> check Synchronize Line and Bar Axis
This will make both scale values same.

SQL-Developer 4.0.0.13.80 Bug? No negative values for axis scale accepted

I reported this problem already for the versions EA1 and EA2 of SQL-Developer 4 (4.0EA1 No negative values for axis scales in diagrams) but it still exists in 4.0.0.13.80: Even if it is now possible to define the minimum and maximum values for the y-axis of a diagram, I found no way to enter negative values for the minimum value. Neither -100 nor (100) is accepted. The value always switches to 0. I have a report which shows values from -97 to 387. Automatic scaling sets the y-axis from -200 to 500 but I would prefer a scale from -100 to 400. How is this possible?
btw.: the German translation for "scale" in the diagram settings is bad. It is translated with "Nachkommastellen" but it should be "Skalierung".

In 4.0EA2 this topic is still not fixed.

Chart options: Y axis scale

Hi,
I created a bar chart for a report that simly displays the count for each distinct value of a field. I would want the Y scale (which displays the count) to only present integer values (its a count, so it's obvious there can't be any non-integer values). Currently it's set to auto select the range and the number of divisions, for which the range it's ok but the divisions don't always come out as all integers. From what I can see, the only way to do this would be to set the min to 0, max to the max count on the report (which is normaly what the auto range does), and the number of divisions as the max count minus one. I don't really see any other way. Apparently there's no way to do this dynamically (like in a formula), and I don't think I can use static range values. Is there any way to do this? I just want to confirm what I know and see if there is any other way to do it.
Also, this is probably not the forum to post this, but just in case, is there any way to do this programatically in code without needing extra libraries or extra tools?
Thanks,
Diego

First of all, by static and dynamic data, do you mean the options for the chart?
Also, I don't want to display the max count on the chart. I would just like to use it on the options for the chart's Y axis as the max value, although I don't think I need to, since the auto scale already does that. I think the only thing I should need is set the number of divisions to display on the Y axis. For example, if the chart has two bars, one for lets say color red, and one for color yellow, and lets say on the data there were 4 red and 6 yellow. So the chart will have two vertical bars, one for red going from 0 up to 4, and one for yellow, going from 0 up to 6. The chart will automatically make the range on the Y scale go from 0 up to 6, but it might make the divisions at say 1.5, 3, and 4.5. But I would like it to not use decimal values for those divisions, instead only divide the axis on integer values, like on 1, 2, 3, 4, 5. To do that, from the options the chart gives me, I can do it by setting a specific number of divisions on the axis (in this case it would be 5 divisions). I just want to know if there is any way I can set that in a formula or something, of if it just has to be the same value for every report (without having to change it directly on the Crystal Reports editor, because the reports get generated automatically with different sets of data).
Thanks,
Diego

How do I set the default x-axis scale in DIAdem View?

Hi everyone:
I look at large amounts of data (i.e. many different data files every day), and I am trying to load and view them quickly and efficiently. Currently, when I have data sets loaded in the "Structure" tab, and I click and drag a numeric channel over to the 2-D plot, DIAdam automatically scales the x-axis from 0 to 60, when the numeric channels can be anywhere from 50 000 to 100 000 entries long. I now use the roller on my mouse to zoom out for five minutes before seeing the entire data set. My question is is there a way to re-set the default x-axis scaling so I do not have to zoom out each time I plot a numeric channel?
Solved!
Go to Solution.

Hello Peter!,
The DIAdem VIEW windows will always auto-scale to the full range of the values on the X-axis when you drag data into a new window.
You have several options on how to quickly get to the range of data you wish to see.
Right click on the LEFT edge of the data you wish to zoom into, HOLD the mouse right mouse button and DRAG the mouse to the right side of the section you wish to zoom into. DIAdem will automatically show the section you have selected in a zoomed view in that same window
Result:
Alternatively, you can double click on the VIEW window and check the "Manual X-Scaling" box and then enter the exact values you wish to zoom into
Also, you could use the Band Cursor from the toolbar, move and resize the Band in the VIEW window and then use the "Scroll in Cursor Range" icon to zoom into the area of the curve you are interested in.
These are just a few ways you should be able to accomplish what you have described in your post.
Let us know if you have additional questions ...
