i have mad a simple diagram with some standard values.
i placed 3 open fields in there with each next to them a button
what the problem is that i need to be able to give field a, b or c
A number and than click on the button that will set the diagram on the right Y and X value.
this is the formula to calculate the right position in the diagram:
Y = ax2 + bx + c
i know that i prob only need to figure out how the diagram works with the buttons but il hope i find out this way.
thx in advance and sry for my weak english.
