According to my current requirement I need to create graphs where I read some part of input from CSV & the rest part of the input is calculated by using different Formulae.Can i get such kind of graph using Flex Professional.Can any one suggest better ways to achieve this.I request to forward any examples of this type.
I don't believe that any of the Flex built-in charts allow this. You may find another commercially available package. The simplest way is to decide how far along the x axis you want points to go, and then generate some data points with the formula you have selected. Depending on your chart type you then have other options, eg a line chart allows you a few different options for interpolating the lines between points (flat segments, curves etc). Depending on your formula you may have to be careful about singularity points where the y-value might go off to infinity.
Here is an app I made that uses formulas to create line charts. Changing the parameters, mostly Acquisitiion Budget and Retention Budget, updates the charts. Let me know if you have any questions.
