referencing table data into a plot function?

[Erikbernhart]

Hi all, i wonder if there is a way to reference data from a table into a plot function?

The table i made depends on the heigth H and shows for this example bending moment, 2nd order bending moment, required rebar and default rebar per meter heigth. some of these calculations require a lot of code, therefore i would like to " just plot" the values from the table. Is that doable for a variable table size depending on the height? making a switch function for in this case σtrek should be doable, but required rebar depending on heigth H and width D seems a bit tedious to pour into a single function.

therefore just having a plot from H and σ would be ideal, but i dont know if thats possible.

Hi, you can wrap values with take/line/spline functions and plot them. See these examples:

thanks for the advice, but still don't think that is useful to use data from a table that i already made.
I think i'm on the good way with the below switch functions to make visible where there is enough rebar and where not yet.
appreciate the reply

Hi, Erik! Do you mean to reference the Html table?

Actually, Html is not processed by the Calcpad engine. This is performed afterwards by the browser engine when the output Html is sent to it. The table does not actually exist before that.

So it is not possible to do that, unless we make Calcpad to process Html, which is a very heavy task.
The proper way is to first organize your data into vector-like functions, such as Take/Line/Spline, and then generate the Html table via loops. Also you can use the same data to generate the plots. Check this example please:
https://github.com/Proektsoftbg/Calcpad/blob/main/Examples/Demos/Double%20Interpolation.cpd

To use Html to structure Calcpad data is not a good way in general and I do not want to encourage that. It is complicated and error prone. Html is an output/reporting feature. The best way to represent table data in Calcpad will be vectors and matrices, which are going to be ready soon. There will be also an option to read them from CSV files or Excel.

Hi Ned, yea i meant exactly that.
I kind of looked for an excel way to make a scatterplot of a range of x and y values, which i allready had/made in the calcpad table.
now i see that is not gonna work.

the table do is made from loops, where different code runs depending on H in relation to three heigths( H1, H2 and H3.) etc.
im not too good in the spline vector like functions yet, but will look into it.

thanks a lot
