Re: A new ternary graph implementation

Hello Marc Thank you for your reply and comments. Perhaps I haven't explained myself clearly enough. I still expect to be able to use three variables, X, Y and Z in a Ternary Chart, but the chart code will automatically convert these to three relative variables using the following formulae: X% = X/(...

A new implementation for Ternary Graphs

The current Ternary Series implementation in TeeChart needs a revamp. It does not suit a lot of users who wish to plot data in a similar format to a regular X-Y plot, without having to implement a lot of special code. A ternary plot is basically an X-Y plot, as there are only 2 independent variables...

A new ternary graph implementation

As you know, I am quite disappointed with the Ternary Series implementation in TeeChart. A ternary plot is simply an X-Y plot, as there are only 2 independent variables (Z is always equal to 100 - X% - Y% where X% = X/(X+Y+Z)*100 and Y% = Y/(X+Y+Z)*100. This means there is no need to use 3D charting...

Re: Ternary Graph Assigning the Weighting parameter

Hi Marc I am pleased to report that we are now able to create ternary graphs with the legend in the format we require. Thanks for all your help. I have two further questions: 1. User-customisation of the legend position and size. I anticipate that users of our application would like to position the ...

Re: Ternary Graph Assigning the Weighting parameter

Hi Marc I have downloaded and installed the modifications, which appear to have fixed the problem of the Weight parameter being incorrectly assigned. I can now generate a ternary plot but am having great difficulty with generating a customised legend. I have attached an XY plot showing the type of l...

Re: Ternary Graph Assigning the Weighting parameter

Hi Marc Thank you for your email. In my previous post, I was trying to explain that any point on a ternary graph can be plotted on a normal XY chart that has the left axis at an angle of 60°. The B% value is plotted on the bottom axis (with a left-to-right scale of 0 to 100) along a line parallel to...

Re: Ternary Graph Assigning the Weighting parameter

Hello Marc Thank you for your reply. When do you think the revised code will be available? I have compared our code (both for a line series and a ternary series), with the test program provided by you where data is loaded from a csv file. In our code, the series is empty, even though the datasource ...

Re: Ternary Graph Assigning the Weighting parameter

Hi Marc Thank you for your reply. A ternary graph requires three values to calculate relative percentages, but only two values need to be plotted on a ternary graph as the third value is automatically 100 - A - B (working in percentages) as you state. If you use a regular XY chart with with the Y va...

Re: Ternary Graph Assigning the Weighting parameter

Good morning I am still having great difficulty in producing a ternary chart by code. I have attempted to implement the various events of the Ternary Chart test program in case I am missing some important steps, but to no avail. I acknowledge that I am using components that you do not use, but I sti...

Re: Ternary Graph Assigning the Weighting parameter

Good afternoon Yeray Thank you for your detailed reply - sorry for the delay in replying. I am still having problems getting a ternary graph to draw. I have attached the code I use. When I run the program, selecting a single series, I just get a blank chart with a title, but without axes, vertex tit...

Re: Ternary Graph Assigning the Weighting parameter

Good afternoon After a long break, I am back again, still trying to get ternary graphs to work. I am writing to express my disappointment in the implementation of Ternary Graphs. We use ternary graphs to display the relationship between three data values in exactly the same way as we use regular XY ...
