Problems with Gantt Chart

Hi,
I have a Gantt Chart in my page, but there is something wrong with the scales; the major scale says, for example, "Monday, Oct 12", but the minor scale says "S" for sunday and then the major scale says "Tuesday, Oct 13" and the minor "Monday" and so on; they doesn´t correspond to each other... This is just happening in spanish, in english everything is fine, I don't know what can I do to fix this.
I have another problem in the same Gantt: one task has "16/10/2009 08:00:00 a.m." for start date and "17/10/2009 08:00:00 p.m." for end date, which gives a duration of 2 days, but in the gantt it is displayed as a 3 days duration!! this happen for every task in the gantt. I've been testing and I found that if I change the end date to "17/10/2009 06:00:00 p.m." (just changing 8 to 6 pm) the duration is displayed just fine, with the 2 days it should be. Actually this strange behavior happens only when the hour is equal or grater than 8:00pm. I've searched in the developers guide but it doesn't say anything about this; I don´t know if the OAF Gantt use some e-business parameter, or something; I really don´t know what can be happening.
I hope you can help me!
Thanks and regards,
Carlos V

Not sure about changing the scale at runtime but from what I've learned, if it can't be done in Crystal Reports itself - it can't be done via code. And in CR the only way I know of is to do the multiple charts in multiple subsections and conditionally suppress based on the number of records (Projects in your case).
You could go to the development forum and ask the question about doing it programatically.

Problem with gantt chart displaying - Apex4.2

Hi I'm using Apex 4.2 on localhost and
I have got three tables: employee, engineer, dates
-> engineer table is a specification of employee table, that means in employee you can find also the
names of the engineers. Engineer only has an additional attribute.
Here's the structure of the three tables:
employee (e_id, lastname, surname....)
engineer (e_id, attribute)
appointment (a_id, e_id,start, end)
Now my problem: By using the gantt chart the xml doesn't want to show the names of the engineers.
If I only use this sql statement everything works but I only have the e_id from my engineer table:
select
null link,
a.e_id,
(select e_id from engineer where e_id = a.e_id) Engineer,
null parent_id,
a.start,
a.end
from appointment a
If I try to use this statement in order to see the names of the employees no chart will be shown,
only xml error:
select
null link,
a.e_id,
(select emp.lastname from employee emp, engineer e where emp.e_id = e.e_id and e.e_id=a.e_id) Engineer,
null parent_id,
a.start,
a.end
from appointment a
I also created a view which combines the lastname from employee and the e_id from engineer
but same problem.
If I try:
select
null link,
a.e_id,
(select e_id from gantt_view where e.e_id=a.e_id) Engineer,
null parent_id,
a.start,
a.end
from appointment a
Then I'll see e_ids in my gantt chart but if I want to see my employee names
with this statement:
select
null link,
a.e_id,
(select lastname from gantt_view where e.e_id=a.e_id) Engineer,
null parent_id,
a.start,
a.end
from appointment a
Nothing is shown on the gantt chart.
I tested all sql statements on sql developer.
There I was able to see my employee names.
But for gantt charts it doesn't work.
Any solutions?

Great!
Of course, hard to diagnose when there's nothing to see.

You are correct, the syntax outlined in the error message is incorrect, and I've logged bug 9799373 to track this.

Can you show us the query you are using?
Oh. And what are the data types and lengths of your data?

Problem with Gantt chart data (not a newbie)

Post Author: wbvczar
CA Forum: Charts and Graphs
I am pulling data from an SQL 2000 database that stores the date as UNIX time in a string field. Once I pull the data into Crystal via a Command, I then create a formula to convert to DateTime format. The problem is that when I enter this formula into the Chart Expert, it wants to count it instead of seeing it as a Date field. Is the problem because the original field format is not a DateTime field in the database?

Post Author: wbvczar
CA Forum: Charts and Graphs
The formula (actually a function) is quite detailed (and lengthy) to compensate for daylight saving time changes. I have posted it below, but I can verify that it is not splitting out the date and time separately.//Function (numberVar v1)//date(1970,01,01)//Truncate((v1/(606024))-(5/24))Function (numbervar v1)//formula to adjust for UNIX time//HD stores dates as number of seconds since 1/1/1970 in Universal or GMT time. //convert from seconds to a date, //then convert to EST //finally, validate date for daylight savings time // convert ARS date from # of seconds since 1/1/1970 in Universal (or GMT) timedatetimevar GMTdate := datetime(1970,01,01)(v1/(606024));//this equation tells the system when daylight savings time starts: datevar DaylightStarts := if DayOfWeek ( Date (Year (Today),3 ,8 ) ) = 1 then Date (Year (Today),3 ,8) else if DayOfWeek ( Date (Year (Today),3 ,9 ) ) = 1 then Date (Year (Today),3 ,9) else if DayOfWeek ( Date (Year (Today),3 ,10) ) = 1 then Date (Year (Today),3 ,10) elseif DayOfWeek ( Date (Year (Today),3 ,11) ) = 1 then Date (Year (Today),3 ,11) elseif DayOfWeek ( Date (Year (Today),3 ,12) ) = 1 then Date (Year (Today),3 ,12) else if DayOfWeek ( Date (Year (Today),3 ,13) ) = 1 then Date (Year (Today),3 ,13) elseDate (Year (Today),3 ,14 ); //this is when it ends: datevar DaylightEnds := if DayOfWeek ( Date (Year (Today),11 ,1 ) ) = 1 then Date (Year (Today),11,1 ) else if DayOfWeek ( Date (Year (Today),11 ,2 ) ) = 1 then Date (Year (Today),11,2 ) else if DayOfWeek ( Date (Year (Today),11 ,3 ) ) = 1 then Date (Year (Today),11,3 ) else if DayOfWeek ( Date (Year (Today),11 ,4 ) ) = 1 then Date (Year (Today),11,4 ) else if DayOfWeek ( Date (Year (Today),11 ,5 ) ) = 1 then Date (Year (Today),11,5 ) else if DayOfWeek ( Date (Year (Today),11 ,6 ) ) = 1 then Date (Year (Today),11,6 ) else Date (Year (Today),11 ,7 );//The timeadj equation adjusts things for daylight savings & time zone // if today is less than the 1st Sunday in April, or greater than or //equal to last Sunday in October then adjust 5 hours, else if DST then 4numbervar timeadj :=if (GMTdate < DaylightStarts) or (DaylightEnds <= GMTdate) then 5 else 4;//put it all together and we have datedate(GMTdate-(timeadj/24))

Regarding Pages charts, when I try to 'build' a 3D chart all I get is little dots but not graphics. No problems with 2D charts though. Guess my question is "Help?"

Regarding Pages charts, when I try to 'build' a 3D chart all I get is little dots but not graphics. No problems with 2D charts though. Guess my question is "Help?"

Sorry for the delay getting back to this.
Thanks to Fruhulda and Peter for their comments regarding the refusal of Pages to let me make 3D charts.
In answer to the questions put to me in this regard :
1. Pages version : Pages '09 v.4.1 (923)
2. Mac O/S :          v.10.6.8
3. 3D chart :          Can't find a 'name', but upright bars with rounded corners ???
4. Moved apps :    Not that I'm aware of! All should be as installed off the disc.
5. A note :              I have been able to create these in the past - related to a SW update?
                      and ... can create these charts perfectly in Keynote (go figure).
Thanks to all.

Problem with displaying chart data

Hello everybody,
I have problem with displaying chart data correctly. I'm using a cartesian chart with DateTimeAxis. The stockdata I'm using is for half a year and
with ticks for every day. The problem is, that Flex displays the data of february in march together with the data of march. I have added a picture
to show the result. The second column of the grid is for february and the third for march.
Could anybody help me with this problem. Thanks in advance.

Hi Chris,
thanks for your reply. Here you get the source code:
The following method creates the LineChart:
        public function init():void
            model.upperChart = this;
            model.upperChartStyle.setChartViewStyle(this);
            this.hAxis = new MyDateTimeAxis();
            model.upperChartData.configureHAxis(this.hAxis);
            this.vAxis = new LinearAxis();
            model.upperChartData.configureVAxis(this.vAxis);
            this.vAxisTitle = new Label();
            this.vAxisTitle.text = model.upperChartData.getVAxisTitle();
            model.upperChartStyle.setVAxisTitleLabelStyle(this.vAxisTitle);
            this.vAxisTitle.x = 10
            this.vAxisTitle.y = 0;
            this.addChild(this.vAxisTitle);
            this.myChart = new CartesianChart();
            //remove default datatip
            this.myChart.showDataTips = false;
            this.myChart.x = 10;
            this.myChart.y = 0;
            this.myChart.width = 768;
            this.myChart.height = 196;
            model.upperChartStyle.setChartStyle(this.myChart);
            this.addChild(this.myChart);
            //Remove line shadow
            this.myChart.seriesFilters = null;
            this.myChart.horizontalAxis = this.hAxis;
            this.myChart.verticalAxis = this.vAxis;
            this.hAxisRenderer = new AxisRenderer();
            model.upperChartData.configureHAxisRenderer(this.hAxisRenderer);
            this.hAxisRenderer.axis = this.hAxis;
            model.upperChartStyle.setHAxisRendererStyle(this.hAxisRenderer);
            this.myChart.horizontalAxisRenderers.push(this.hAxisRenderer);
            this.vAxisRenderer = new AxisRenderer();
            model.upperChartData.configureVAxisRenderer(this.vAxisRenderer);
            this.vAxisRenderer.axis = this.vAxis;
            model.upperChartStyle.setVAxisRendererStyle(this.vAxisRenderer);
            this.myChart.verticalAxisRenderers.push(this.vAxisRenderer);
            model.upperChartStyle.setVAxisDataLabelStyle(this.vAxisMinLabel);
            this.addChild(this.vAxisMinLabel);
            model.upperChartStyle.setSeriesStyle(model.upperChartData.series, model.upperChartData.shares);
            this.myChart.dataProvider = model.upperChartData.dataProvider;
            this.myChart.series = model.upperChartData.series;
The data for dataprovider and series you can see in attached file dataprovider.xml.
xfield is equivalent to timestamp
yfield is equivalent to absolute
I think the problem could be the configuration of the datetimeaxis. The following method shows the parameter for the datetimeaxis:
        public function configureHAxis(axis:MyDateTimeAxis):void
            axis.parseFunction = UtilityClass.parseYYYYMMDDHHNNSSString2Date;
            axis.dataUnits = "days";
            axis.dataInterval = 1;
            axis.title = "";
            axis.minimum = new Date(UtilityClass.parseYYYYMMDDHHNNSSString2Date("2009-01-07 00:00:00").time);
            axis.maximum = new Date(UtilityClass.parseYYYYMMDDHHNNSSString2Date("2009-07-06 00:00:00").time);
And finally you get the function, that I'm using for string to date conversion:
        public static function parseYYYYMMDDHHNNSSString2Date(input:String):Date
            var result:Date = new Date();
            var year:Number = Number(input.substring(0,4));
            var month:Number = Number(input.substring(5,7));
            var date:Number = Number(input.substring(8,10));
            var hours:Number = Number(input.substring(11,13));
            var minutes:Number = Number(input.substring(14,16));
            var seconds:Number = Number(input.substring(17,19));
            result.setUTCFullYear(year);
            result.setUTCMonth(month-1);
            result.setUTCDate(date);
            result.setUTCHours(hours);
            result.setUTCMinutes(minutes);
            result.setUTCSeconds(seconds);
            return result;
I hope that will help to locate the reason for the wrong chart visualization.
Thanks for any help.

How to create new view without interlinking with gantt chart or resource views

ok clear
one another question
In msp how to create new view without interlinking with gantt chart or resource views

Hi Shiv PMC--
I splitted your question above in another thread in order not to have a huge thread with many topics in it.
That being said, I'm not sure to understand. A view is just a manner to display MS Project data with columns. A view can have a table with column (left part) associated with a Gantt chart. It can also just contain a table with no Gantt chart (like the task
table) or a table with a timephased grid (resource and task usage).
Please give us more information, maybe with a concrete example so we can help you.
Hope this helps,

I have a problem with a chart refreshing after its bound data provider changes.

I have a problem with a chart refreshing after its bound data

would expect the chart to redraw, but it still looks the same. I
even inspected the debugger to see if the slice had taken place and

Any ideas coding friends?

Just use the ArrayCollection's removeItemAt, and it should
handle the event

Problem with waveform chart: time scale does not show time correctly

Hello,
I have some problems with a chart.
I want to display some data and the time between two single data can vary. It is something between 50ms and 500 ms.
The problems I have:
1. The time is not shown correctly in the chart (allways 2:00:10 instead of the current time)
2. the data points in the chart have a distance of 1 s (x-scale). That is not correct.
I have tried several things but I thinkt I am on the wrong track.
Could you please help me?

I have a data array and the last 10 seconds of the data are displayed.
The array size is maximum 150 and that is more than I need to display. If new data is inserted, the oldest gets deleted.
I wonder if this style is efficient?
The time is stil not displayed correctly in the graph. Why does it always show 2:00:00 ?

Problem with Bar Chart using Date Data

I am trying to make a simple horizontal bar chart as a Gantt chart. I am trying to set the min and max for the X axis but it is acting strangely. As you can see in the screenshot below, I set the min to 1/1/2000 but the chart uses 9/28/2011. Similar problem with the max setting. Am I doing something wrong here? Can anyone duplicate this? Anyone have a solution other than this workaround I am now using (which I assume will break my chart once Apple fixes this problem)?

BadUnit,
I assume Numbers, like me, is confused why you would set min/max limits that do not include the data?
I do get the same result as you when I enter the time range for the chart as 1/1/2000 thru 1/1/2004.
I even tried making a separate table for the chart:
There is definitley a problem.
When I enter, what I think are reasonable, min and max dates for the chart
min = 1/1/2013
max = 12/31/2015
The chart adjusts like this:

Problem with Gantt table (Business graphic)

Hi everybody,
I got a problem with an gantt table (Business graphic) in an old project. This gantt table is used to display the timeline of used ressources. The Problem here his that, if the last row of the gantt table is filled, this row will not be displayed correctly. The line will only be filled up half of the height the row has and the row will be divided by a horizontal black line.
If somebody has an idea about fixing this problem, that will be great.

PROBLEM WITH OVERLAID CHART

Hello everyone, I'm using flex 2 and I have an application
that shows a ColumnChart to the user, and let the user choose the
chart type, that can be overlaid, clustered, 100% or stacked... And
I'm having problem with the overlaid type, because in the chart
I've put 4 ColumnSeries, and when the chart is rendered, some of
the columns appear in front of the other ones hidding it...
It doesn't solve my problem to change the order of the column
series because the order of the bars will change for all the
items...
What should I do to have the overlaid chart working
perfectly, showing all the columns correctly?
Thanks in advance.

Seems to simply be a problem with your data. See this
code.

Hi,
Do you want to change the label???
1. Just right clicl your graph
2. in the properties window go to 'Scales' tab
3. select the Axis, and change the name.
Is this the solution regarding your issue....
Or
do you want to change the domain from Time or Frequency...??

Problem with Pie Chart

Hi Experts!!
I've a little problem with a Pie Chart, I want to present a Pie Chart with 3 values which are defined on the Data Series, when I deploy I get the message: "Expected exactly 1 data series in XXXXX chart. Extra data series ignored". I don't understand why, because if I try to do a Column Chart with the same information, it works Ok!
