When I zoom within the Teechart, the ZoomRect has false positions. The x-pos always has an left offset (for exam...

Teechart.NetV3: SVG Export does not Work

Hi, There is an error in the SVG Format routine if you use clipping to draw the series (as recommend in the faq). In addition it would be useful if the generated svg root node declares the svg namespace ( xmlns="http://www.w3.org/2000/svg" )eg: <svg width="1000px" height="581px" style="text-antialia...

It's version 3.2.2868.26903 this should be the latest available release. i have located this bug via reflector therefore the source can be different in the original version. you can look at the panning.Check method: int num; if (this.x0 > this.x1) { num = this.x0; this.x0 = this.x1; this.x1 = num; }...

Zoom with custom axes

HI, I'm working with TeeChart.Net V3. How can i zoom when having only custom axes ? e.g. 2 custom axis one on bottom position and one on left position the standard axis are not used (because their position algorithm is different). I think i have to do the calculation by myself, but how without writi...

Hi Chris, However, from what you told me I was expecting the Thread.Sleep to produce a noticeable visible difference between the two buffering methods, but I could detect none. On the first run of the form, neither chart showed anything before the first time appeared and and both only showed when th...

hi chris, this solves the problem of flickering. but there is also another problem: if the drawing is slowly (e.g uncomment the Sleep call in Draw method) and you resize the window, then the application isvery unrespondable. maybe i have to tell you, that the current tee-chart implementation has the...

Hi Chris, i'm aware that this solution is not really finished, but its the correct approach. flickering is only because the OnPaintBackround method is called before OnPaint. this method clears the background (gray) therefore you see a flickering. the automatic double buffering calls OnPaintBackround...

Hello Christopher, My first impression is: These controls only prevent flickering when painting is slow (in OnPaint). The solution for teechart would be to paint from a back-buffer in case of a simple background refresh. i have seen such implementations but don't have time this week to make a more d...

State of manual double-buffer implementation ?

A few months ago there was a discussion in this forum concerning the useless chart updates of teechart.net when a redraw of background is required. this could be solved (i think easily) with a double-buffer implementation. see subject http://www.teechart.net/support/viewtopic.php?t=6074&highlight=do...
