Re: Pinch to Zoom

Hi, Yes, for sure we're not seeing the same behaviour; it may be idiosyncrasies of different devices. Our modifications, making sensitivity (zoom speed-response) publicly accessible will help. Note though, as a test, that if you place a touch location on either side of the bar, bar 5, and keep the r...

Re: Pinch to Zoom

Review of the current WPF touch functionality. - Scroll mode, one finger-touch. This seems to work correctly when tested, speed of response, ie. plot movement in relation finger location, appears correct on our test device. Scroll correctly resets on double-tap. - Zoom mode, two finger-touch. This a...

Re: TeeCahrt 4.2020.8.28 & 9.16

Hello, emSize is often used for Font sizing. It could be going on in a call to TeeChart but there is no TeeChart parameter that I can find with the name "emSize". If you put a break point in, do you see any TeeChart classes in the call stack? Is there any clue that this is being caused by TeeChart? ...

Re: TeeChart Cleanup

Hello, Garbage collection should handle most general objects itself but if you create any other specific items then you could choose to clear them, for example custom axes. Are you experiencing any memory leaks issues that you think may be related to TeeChart? We can investigate if you consider that...

Re: VirtualModeData column sorting, vertical scroll bar and Page Up and Down key

Hello, Re. "The Key Page Up moves the cursor row up 10 rows. Where is the number of rows to move set?" That is currently fixed at 10. We'll add a property to control that. ( http://bugs.teechart.net/show_bug.cgi?id=2352 ) Re. The Key Page Down moves the cursor row to row number 11. This is not norma...

Re: Very long canvas - print fail

Hi, Found it. There is a maximum pixel limitation setting in TeeChart, used to control out-of-bound axis calculations, that we'll need to review. It's currently set to $7FFF (decimal 32767). Whilst we check what to do, if you have the sourcecode version you can modify it as an interim workaround: ie...

Re: Very long canvas - print fail

Hello, The metafiles don't seem to have saved correctly in the zip you posted, but we'll take another look at this to see if we can shed any light. With the current version of TeeChart the plot cuts the last data points in the metafile at exactly 32,767 pixels, the known limit for a metafile. The ca...

Re: Editor in code?

Hello,

There is no editor for the HTML5/Javascript version. It is possible to code editor options for runtime as in these examples:

Re: [2020.30] .Net Framework 3.5 Win10

Hello,

It shouldn't be necessary to uninstall Framework 4.0 to install v3.5, they can run side-by-side.

Re: Assigning Ternary Vertex Titles

Hello,

Thankyou for the bug reposrt. There seems to be a problem with the serialisation of the values.

You can modify them by code in this way:

Code: Select all

Series2.VertexTitles[0].Text := 'My A Title';
It has been logged here to be fixed.

If you export to metafile in both cases there may be a clue to the different behaviour.

Re: Winapi DrawText on chart no longer use canvas settings

Hello,

When using GDI+, TeeChart uses the GDI+ DrawString method internally.
