Hello Sandra, sorry for my late delay, now i can give you an answer to your question. No, your code does not work. Setting a fixed width but don't know how much space the labels realy require is not a good solution. In my real world progam i have 1 to 100 possible legend entries each with different ...

Hello, till last week we used TeeChart 3.5 (3.5.3105.20151) for over 4 years now but finally we upgraded to version 4.1 (4.1.2011.6283). In one of my first tests i found an issue with the LegendScrollBar tool. The size of the legend does not fit anymore and i have not found a usefull way to fix the ...

Hello, is it possible to work with TeeChart 2008 (3.5.3105.20151) and use a license of the current release? We have a plugin based module which uses the old version of TeeChart. Now a customer wants to create a plugin with TeeChart for our module, but he should have its own license. Is this possbile...

AIS

Hello Sandra,

thanks for the help. Now it works like expected

AIS

This should also work

Code: Select all

this.tChart2.Axes.Left.Increment = 200

AIS

Hello Sandra, yes, this works but it is not clear for me why it does. I mean, it should also not work within the load event,but why it works also without any changes? By the way the downsampling is only usefull if you choose a fastline series with DrawAllPoints=False otherwise the drawing of the sec...

AIS

Hello, i have tried to test the downsampling functionality within a simple silverlight project. During implementation i recognized a strange behaviour for this function. This behaviour occures with the winforms and also with the silverlight assembly. I try to explain this with a simple winforms exam...

Hi Yeray,

what about something like this

Code: Select all

enum OriginValues
{
/// <summary>
/// before: UseOrigin = true
/// </summary>
Zero,
/// <summary>
/// default value
/// before: UseOrigin = false
/// </summary>
NegativeInfinite,
/// <summary>
/// new value
/// </summary>
PositiveInfinite
}

AIS

for example like this:

Code: Select all

CustomBar cb = new CustomBar(tChart1.Chart);
cb.Add(0, 1);
cb.Add(1, 2);
cb.Add(2, 0);
cb.Add(3, 4);
cb.SetNull(2);

AIS

I don`t know how the datatable tool visualize the case if you first add a 0 value and then call SetNull for this point. Anyway, the bar is not shown as a small line

AIS

Hi,

for 0 values you can use the "SetNull" method. I use it to avoid 0 value artefacts like you told.

AIS

Hello Sandra,

i could not update to v4 yet, because a lot of testing must be done after that to ensure the same functionality. Thanks anyway, i will try it next time

AIS

Hello Narcís, i dont use v4 of TChart, i use v3.5 and i try the postet solution of the linked thread. The region which is automatic redrawn (only the annotation) through invalidate, causes also a high delay of the cursorttool (fastcursor true/false), that doesn't look good. I think this can not be a...

AIS

Hello, i have a chart with some fastline series and a lot of data in some cases (>10.000 each series). Now i want to give the user the opportunity to move a series with the mouse in the chart per drag&drop. During the move, the series should follow the mouse and at the end the original series, x and...

AIS

For a correct zoom in and zoom out calculation step wise there is a good explanation from narcis within this thread
