amCharts & amMap blog

Since v 1.3.2 Line & area, Column & Bar and Scatter & Bubble can have logarithmic scale axis instead of standard linear. In logarithmic axis equal distance along it represents an equal percentage change. It is very useful if you want to present large scale data on the same chart.

To make your axis logarithmic, all you need to do is to add:

<logarithmic>true</logarithmic>

in your axis settings.

Line & area chart can have logarithmic y left and right axis, column & bar chart – value axis, scatter and bubble chart – both x and y axis.

Today I released v 1.3.1 of all charts. The main new feature is that now you can print charts with JavaScript. Check js_example.html to see how it works.

There are two functions for printing:

flashMovie.print();

and

flashMovie.printAsBitmap();

In most cases the first one, print() function will produce a better result. However if you have rotated by 90 degrees labels, transparent objects or background images, it might be better to use the second function.
