Paul,
What is the limit on number of curves with %PL if they are built as "independent" ? I tried more than 10 curves but failed. I remember we discussed here that it would be great to increase this. Is it doable or needs much work ?

Tried to reproduce this nice plot made ages ago using professional contour software. The greatness of it is that it actually displays the evolution movie in one static XY plot !

Dan,

This should work, the thing to remember is that if n_graphs > 10 and more than one related call is made to winop@ then the value of n_graphs must be included in the first call to winop@.

The following sample program illustrates a way to draw multiple curves on one set of axes via a callback function. Details can be found in cwplus.enh.

Very cool, thanks, Paul
Here is your example with 50 curves added:

Ken,
Your comment how to make n_graphs > 10 usual way i did not understand, sorry . I have done it this way which does not work if i use Nt (number of curves) more than 10. here is working example with 10

[DanRRight]

And if i just change Nt and n_graphs to 12 and add two more pairs of Xmp, Ymp to make 12 curves then i got crash with the error message "Invalid n_graphs in %PL specification". Here is the full text

Dan,

Here is a modification to your second example that now works as expected.

Ken,
Wow ! Gazillion monkeys randomly hitting keyboards would probably earlier write "War and Peace" than me logically finding this so counterintuitive solution ! Are

[Kenneth_Smith]

Dan,

This works without calls to winop@ before the i=winio@ function call:

[DanRRight]

So what was wrong in my 12-curve example versus working 10-curve example? The 2-curves were working, 3-curves were working, 10-cureves were working and abruptly more were not?

!-----------------------------------------
Not related question: In %PL we set the colors of curves this way

CALL winop@("%pl[colour=#110011]")

How to extract this color for using with draw_filled_polygon@ or draw_symbols@ which use RGB@() for setting colors?
How translate #110011 exactly to what rgb@ gives ?

Or if put this different way, is it possible instead of

CALL winop@("%pl[colour=#110011]")

to set the colors somehow this way

CALL winop@("%pl[colour]"), rgb@(x,y,z) ????

[PaulLaidler]

#110011 is equivalent to RGB@(17,0,17). 11 is hexadecimal so becomes 16+1 decimal. The order is the same so red is #ff0000 and RGB@(255,0,0).

Here is some code that does the conversion...

Thanks Ken and Paul for the hints and tips

[DanRRight]

Here is what i got with multiplot (of course case was different from the one shown in first picture). Ideal for planning experiments

[DanRRight]

I spent a day experiencing another devilry bug after noticing that the order of colors in the plot does not correspond to the order in the time history with numbers at the right. Colors at the right are correct, they correspond to natural palette from violet to red. Order of colors in the plot are wrong. Initial 7-8 times are in correct order with the plot history and then abruptly colors on the plot are turned upside down and start with red down to blue

Tried to change anything but this damn order still persists. If i make small demo like i did above both look in correct order. I used standard method of plotting we discussed with Ken which has strange not yet understood behavior. With Paul's method this would not happen but it is too new to me and i do not feel comfortable yet to jump into it as there could be many other pitfalls

[Kenneth_Smith]

Dan,

For the problem you describe, I would check that each :

CALL winop@("%pl[colour=#110011]") etc

is in the correct order for graphs 1 to N.
