tmp2.png tmp1.png tmp3.png I used this method to draw on the line. I was attempting to use the real values in x, y and z to draw across the chart in each plane. The actual line produced looks perfect but its orientation is wrong. The x and y coordinates appear incorrect in a 3d context. Any advice ...

Thanks, it was a rotation tool causing the problem. Sorry, I didn't realise it was active. The code i'm working on was written a while ago by another programmer so I wasn't fully aware of what was going on. Thank you for helping.

Hi,

I have a surface plot which is designed to display just a planar view and therefore essentially be a 2D grid. Is there a way of preventing the chart from displaying the depth axis when I click and drag it?

Hi,

I tried to install TChart within the RAD Studio 10.2 IDE. The installation appeared to work and the components were available in the tool palette. When I tried to build a program with one of the components an error was thrown reading 'module not found'. How do I get round this?

Hi,

I would like to switch the Border's visible value of a TSurfaceSeries programmatically. I can't find the property to access it. Can someone tell me what it is please?

Hi, I have a feature in my program which animates the surface plot by gradually rotating and elevating it on a loop cycle. The calls to do this are made from a worker thread so that the rest of the program can be freely interacted with. Unfortunately, the reults are slightly jittery and the chart is...

Hi, I have some code in my program which references variables like 'NumXValues' and 'NumZValues' (in the context of a surface plot) in order to set ranges etc. The problem is that the chart seems to update one step late meaning that the values are those of the previous range. I have tried to update ...

Hi, I have a surface plot which can be controlled using the TeeCommander. I also have a thread which animates the plot by sequencing a series of pivots and rotations. If I use the commander to manipulate the plot (the rotation for instance) and then start the animation I find the plot can be moved a...

Hi, I have been attemptong to draw a line (in 3D) across a surface plot using the MoveTo3D and LineTo3D functions. Intuitively, I tried using the CalcXPOsValue and CalcYPosValue to obtain the start and end positions for x and y but I see not equivalent for the z value. I winder if there is a simpler...

Hi, I've noticed that when plotting a very large dataset in a surface plot that almost everything else in the program which involved some sort of animation (e.g. zoom, rotate, spinedit) becomes slow. As these features are built in to the component I can't think of a way to increase performance. Do y...

Hi,

Is is possible to limit the buttons on the teecommander by removing some of its buttons? If so, how?

I am using 'Teechart 2016 VCL Components'.

Thank you, but the problem is when I export the image. You have an option to alter the size of the image. When I do this the detail in the chart (e.g. labels, title etc.) do not re-scale to fit the rest of the image and appear quite small, even though in the plot they look correct.

Basically if i try and export a chart as a large image - say, to fill an entire A4 sheet, the scale is disrupted and the labels etc. appear smaller. Is there a way I can retain the way the chart appears on screen and export it as a larger image (in terms of dimensions)?

Hi,

I find that when I export a chart as an image the resolution decreases, but if I print directly it looks clearly defined. How do I ensure that exported images appear as clearly?
