The Sinclair QL Forum

I want to make a graph os sin(x) vs x In Easel,but the Horizontal axis must labeles as -2pi to 2pi step p/8 etc. I can do it with excel and origin . Can Easel be used for this types of graphs?

mhanias,
Yes, it can (at least partially, and the picture might to be tweaked manually to look like you want)

Note I'm referring to XChange Easel. I hope most of it applies to QL Easel as well.

• Press the Tab (or <Shift>Tab) key repeatedly to increase the number of cells displayed. This increases the accuracy of your curve
• Enter the following formula "figures=sin(2*pi()*(cell-1)/(cellmax-1))". This should display a sin() wave
• Next step does something manually Excell would do automatically: Adding the labels in the right places. Move the crosswire to the first cell, enter F3 E L to change the label to 0, -2pi,... respectively. In case you have too many cells so that the text wouldn't fit here, add free text in the right place using F3 E T

And you'l probably end up with something like that: (I didn't care for text and labels, sorry, and I promise to work on my sense of horizontally)

Thank you very nuch for the Reply. the question is if someone can put the labes aytomaticaly, but I think the desigh of EASEL does not permit it
