TChart CAN draw viewer-facing text with an OpenGL chart
I'm still searching for a way to attach some form of labels that FACE THE VIEWER with an OpenGL TChart. But then I realized that TChart does something suitable all the time! Here is an example: forwardfacingtext.JPG Note that the "normal" text labels for the boxes face what was originally the "front...

Still can't make both points AND text look good
BACKGROUND: SPIN PLOTS I'm trying to create a "spin" chart using TChart. A spin chart lets an analyst view a 3D scatter plot and spin it around by pitch, yaw and roll. Here is an animated GIF that is a good illustration: macspin example.gif With a modest number of points (up to 20 or 30, say), it wo...

Re: Display text in OpenGL mode perpendicular to viewing axis
Hmmmm. Well, it should be simple enough to draw the text labels myself using the onAfterDraw event. 1) If I draw to a OpenGL canvas using onAfterDraw, wil my text still appear to be rotated? 2) I need to know WHERE to draw the text. How do I retrieve the x-y coordinates (in Canvas coordinates, NOT i...

getting points AND labels to look right in oblique view
In a previous post, I wrote that when viewed at an oblique angle, Point3D series show flat rectangles not cubes, and Bubble3D series show flat circles, not spheres. Sandra (site admin) suggested using an OpenGL canvas instead, and gave code on how to do that. Wow, now my series points look stunning,...

Adding points with labels changes axis
I'm creating 2D scatter plots at runtime (since it's not known at designtime how many charts will be needed). When I add points using AddXY without labels, the bottom axis looks fine, showing the scale of values (see top chart, attached). But when I add points WITH labels, the bottom axis shows thes...

3D: symbols, elevation, inertia, and "roll"
To Narcis, thanks for the tip about using the 3D series ... they look great!! But there are some remaining puzzles: * The symbols in the 3D series are flat when viewed at an oblique angle. The Point3D series shows flat rectangles, where one might expect cubes. Similarly, the Bubble3D series shows fl...

Re: How to "reset" theme
The inability to "un-apply" or reset a theme is a serious problem that substantially reduces the utility of this otherwise valuable feature. Some notes: * Choice of some themes appears to set some properties that are not set by other themes. Some examples: * "Facts" sets back wall to alternating hor...

Re: Ternary tweaks
Hi, Yeray and others -- I've created a little demo project (with a runnable EXE and all the source code) that illustrates several tweaks needed to TERNARY plots, including: * obscuring of axis labels * clipped display of lower two VertexTitles * Palette seems to cycle over and over, rather than fitt...

Ternary tweaks
I was delighted to see the new TERNARY series type, and have already made client-dazzling use of it in a project! But there are a few tweaks needed. Please take this as suggestions from an enthusiastic fan who is astounded by how much is in TChart Pro! * Axes -- if a bubble is placed on an edge (bec...

Re: OnClickSeries with TLineSeries selects the wrong point
Hi! Sorry to say, but the problem is certainly more than just an index off by one. To test, I created a chart with several series. As in your example, I set the title according to onSeriesClick, but I also show the series.Name. In addition, I set the title when onClickBackground fires, to more easil...
