Hello Yeray,

very useful, thank You !
In fact it would be nice if this was just another flag/option of TChart.

Hello,

often when a range that needs to be zoomed in is close to an axis its not easy to achieve because the zoom rectangle can
only be started inside the chart axes area. Is there a simple option to enable the zoom rectangle to start outside the TChart axes ?

Hello Yeray,

Great, that piece of code is very useful for other data and cases too.
Thank you very much!

Hello Yeray,

That looks great, thank you very much!
The next question is of course if there is any way to show that plot as a surface.
Could I re-order the data somehow (with increasing X, for example) and then put it into a TSurfaceSeries ?

best regards,

Hello Yeray,

could it be that this data is not suitable for the requirements of TSurfaceSeries?
This is not clear to me, further maybe I can resort the data to make it suitable for this
kind of series, whatever the requirements may be.

Hello Yeray, a TSurfaceSeries doesn't show up at all when adding all the XYZ data and TTriSurfaceSeries doesn't have a WireFrame property. Here is the XYZ text file put in a ZIP file: sph-strain.zip Maybe you have an idea how to get any decent surface picture from this data using TChart ? Thank's an...

Hello, I would like to create this kind of plot with TChart: SurfaceCapture.PNG unfortunately I can't attach the text file with the XYZ data (sph-strain.txt) !? In Matlab / Octave the graphics is created like this: m = 60 n = 60 strain = load ("sph-strain.txt"); # sequence of float. i.e: x,y,z … X =...

Hi, I am using the "AddPalette" call to add a custom color scheme to a TColorGridSeries and a TSurfaceSeries. In fact I want to supply just the colors and let TChart self/automatically distribute the Chart values along the given color values. Is that possible, is there a setting for this ? best rega...

Hello Yeray, I tried your code to draw the bottom axis title, that indeed helps to displace it and making it completely visible. Could you please post the source code for the Left axis title too, taking into account to draw the axis title from bottom to top (not from left to right) ? best regards, X...

Hello Yeray, >I've tried it with v2015.15 and v2015.16 in Android and it seems to give the same result. Could you please specify what two versions to compare? You are right, its only OK when using Tchart VCL in OpenGL mode. Native painting shows indeed the same bug than the FMX version. Will this pr...

Hello, there are problems with axes titles in 3D that got worse with the latest release 2015.16: Foto 08.09.15 11 36 51.png I used the gesture example and added titles for the X-Axis (Bottom Axis), Y-Axis (Left Axis) and the Z-Axis (Depth Axis). What you see is (on a iPhone 6): 1) The titles are not...

Hi Narcis,

Thank you, the Gestures example was very helpful !

best regards

Hi Narcis,

But how do I set the Chart into the zoom or rotate mode, so that it can be zoomed or rotated by the touch and dragging with a finger ?
You are just setting the rotation angle and the zoom % by code in that example, right?

best regards,

Thomas

Hi Narcis,

yes indeed, now that I removed TeeCommander the 64-bit app starts up fine.
Do you have a quick example how to set the TChart in rotation or zoom mode by a button click without usage of the TeeCommander component ?

best regards

Hi Narcis, I just created a new/fresh multi device application and put instances of a TChart, a TSurfaceSeries, a TColorGridSeries and a TTeeCommander on the empty form. When I try to run the 64-bit version on my iPhone6 it crashes too on startup. So this is a showstopper on iOS. Please let me know ...
