Regarding seperate chart series in a chart control

[Sathishkumar Kaliavaradhan]

Hi All

I am using syncfusion version 4.4.0.51

I am showing multiple chart series in a chart control , so that each chart series size will determine by runtime only based on number of series and chart bounds height, below is my code

float height = this.Chart.ChartArea.RenderBounds.Height / (count + 1) - 10;

series.ChartSeries.YAxis.AutoSize = false; series.ChartSeries.YAxis.Size = new SizeF(0, height);

the above code will be called inside the "chartlayout_completed" event

the code throwing stack overflow exception

Can anyone help me... How do i achieve this ?

or How to avoid exception.

reply ASAP.

Thanks and Regards

Hi Sathish,

Thanks for your update.

While showing multiple chart series in a chart control, it is possible to set Chart Area size automatically based on the chart series size at runtime using ChartControl’s ‘BeginUpdate()’ and ‘EndUpdate()’ functions.

Please find the sample attached.

Dynamic Chart size sample

Let me know if this helps.

Thank you for choosing Syncfusion products.

Hi suresh,

i don't know you got my reguirement or not, because i asking chart series in stacking model but you giving example in ordinary chart series add and remove only,

my last mail i mentioned example for stacking model also

chartseries1 height from 320 to 280
chartseries2 height from 270 to 230
chartseries3 height from 220 to 180

set by runtime based on total height of chart and number of series

can you please try to understand my reguirement and then send me sample if it is possible

Hi Sathish,

Kindly have a look at the sample attached which will help you to resize the height of Chart and number of series.

Hi Suresh,

I don't have screen shots right now but i tell you my reguirement

I have chart control in that user can configure number of chart series at runtime (say suppose 3 chart series or may be two ) and i am showing the chart series in stacking model (means seperate chart series one by one in "Y" axis)so that i have to allocate same space in "Y" axis each series , so that i was tried to get the height chart of chart control and get sum of chart series

Each series primary "Y" axis scaling height is set by runtime below is my calculation

Each series primary "Y" axis scaling height = Height of chart / number of series

float height = this.Chart.ChartArea.RenderBounds.Height / (count + 1) - 10; series.ChartSeries.YAxis.Size = new SizeF(0, height);

this code will be called inside layout_completed event that is it but this code throwing stackfull exception for me but same code working in 4.4.0.50 but exception in 4.4.0.51

can you please try to understand my problem and tell me how do i solve ?

Hi Sathish,

I regret very much for the delay in my response.

Please take a look into the sample attached which will help you to set chart axis height by selecting number of series to create a chart like Stacked Y axes chart.

Please let me know if you have any further questions.

Thanks for your patience.

Hi suresh,

whatever example you gave for stack model chart is not stack model.

i don't know you got my reguirement or not but

I repeating the same

1)Actually my problem is to avoid stack overflow exception while setting the axis size in runtime

if possible then only send me the sample and remember "setting the axis size by run time in layout_completed event"

Hi Sureshbabu,

Please run my code attached in previous post , see that it will throws stackoverflow exceptions in setaxis() function

Actually i am using the layoout_compeleted event for allocating space for axis because while form resize then event will fire and get latest height of the chart control then based on height i will allocate to series axis.please run my code and resize the form,see the error

Please correct this problem me as soon as possible because very very urgent for me.
