Hello Smath,

I have noticed that the variable for graphs must be x.
In physical equations the variable is very often the time t.
Sheets would be easier to understand if I could keep the right variable
throughout the formulas and the graph.
I have to enter the the variable in the parenthesis anyhow.
So you will know the name.

This could be combined with the definition of a range,
which was also requested in one of the other posts.

I also have difficulties in operating the 'Scale' for the graph.
I can not scale x-axis and y-axis independently.
If I move the mouse up and down the graph scales up and down.
If I move the mouse left and right the graph scales only down with higher factor.

For me it would be more convinient, if I could assign the min and max values
for the axis in the graph.

Hello.
All that you said about graphs will be added soon.
One remark to functions with 't' variables for plotting - screenshot shows how you could do this:

Thank you for the quick answer and the first workaround.
Could you help me with another graph related issue?

Currently I can't get more than one curve into the graph.
I have seen some samples in the forum where a system of equations is used.

I have entered:
____{sin (x)
f(x):={2 * sin(x)

If I add a 2D-graph of f(x) no curves will be shown.
Is there a trick ?

Those pic's you saw was for the 0.50.4 version of the program.
Last versions of SMath Studio doesn't support multiple graphs into a plot canvas. This feature will be added as soon as possible.
