  Detailed description  
This class can be used to draw a semi-logarithmic chart from multiple data sets.

It is most suited for drawing charts of data sets that have values that grow exponentially.

It can render the linear data set scale horizontally and draw one or more lines from exponential data sets that grow vertically.

The chart image is rendered in the PNG format and is displayed as the current script output. The data set labels and colors are configurable.

 Charts are very useful for sites that need to present data sets in a visual way. The graphical charts help the site users to understand better the meaning of the represented information.

Sometimes the data to be presented grows exponentially. Representing exponential data in a linear chart makes most data points appear condensed on the beginning of the chart.

Semi-logarithmic scale charts are better to represent exponential growing data, as it makes the data appear less concentrated.

This class can be used to draw charts in semi-logarithmic scales, thus making it more adequate to represent data sets that grow exponentially.
