Not enough data points to calculate functions

[nehasaini]

Hi all,

I am developing a software for our client which is interacting with a machine and read values from the machine and plot the graph on PC.

I am using RT-Tools 2D version 1.0.11.

I am using visual studio 5 for this purpose.

The problem which is making me drag my hair is that, when the data points which are received back to the PC from the machine they are not plotted on the RT-Tools 2D at runtime (which is a requirement of the client)

But if I save all the data points in an array or table then make the points to plot, the tool run great.

All the time during plotting at runtime i am getting this error "Not enough data points to calculate functions".

Help me out in solving the problem for getting the Tool to plot the data points at runtime.

Any Kind of help is appreciable.

Thanks
help me out

Dea Neha,
you propably have some calculated series connected to you graph, as e.g. interpolated lines, which require more than one or two data points. The error message you see is fired in this case.
Solution would be
a) connect the calculated series only if required ammout of data are available
b) set a handler for the CalculationError event of the relevant function series. This handler coud handle the case quietly not blocking the application.
If you have any further problems, please send the project and I will have a look.
