amCharts & amMap blog

Some people complained, that sometimes charts display numbers with decimals when their data can be integers only (for example unique visitors). All charts with axes now has <integers_only> option. Set it to true and you will no longer see numbers with decimals.

<integers_only>true</integers_only>

All chart types now has two additional files:

export.aspx and export.aspx.cs

These files are used for exporting charts to images in .net platform.

If you are using .net and want to enable export to image feature, set

<export_image_file>amline/export.aspx</export_image_file>

(or some other folder)

Update:

ASP.NET controls for amCharts released

Since v 1.1.4 Line chart can display stacked and 100% stacked lines and areas.

By default, line chart is a simple line chart to switch to stacked or 100% stacked chart, you have to set type in settings file:

<type>stacked</type>

or

<type>100% stacked</type>

I just released Scatter and Bubble chart. This chart can be used to present different scientific data, also three dimensional data in 2D format.

A lot of users requested these features and here they are – since column chart v 1.1.7.

Gradient fills
Columns and bars can be filled with vertical or horizontal gradients, check these examples:

http://www.amcharts.com/column/chart-with-gradient-fills/
http://www.amcharts.com/column/floating-chart/

You can use a lot of colors to create fancy gradients.

To create gradient, in your graph node you should add:

<gradient_fill_colors>#000000,#FF0000</gradient_fill_colors>

Or you can add the same attribute in data file:

<graph gid="0" gradient_fill_colors="#FFFFFF,#BEDF66">

To define gradient direction, in your settings file, add a child node for <column> node:

<gradient>horizontal</gradient>

Default direction is vertical, so it is not necessarily to add this line if it is OK for you.

Check 4, 5 or 9 examples in the package.

Custom series’ background colors
You can set different colors for some of your series, here are two examples:

http://www.amcharts.com/lib/amcolumn/auto-resizing-chart.html
http://www.amcharts.com/column/floating-chart/

In the first example, background colors behind UK and France are different from the standard background color. And in the second example every person has slightly darker background color.

You can only use this feature if your data file is XML, not CSV. The syntax is very simple:

<series>
<value xid="John" bg_color="#000000" bg_alpha="20">John</value>
………………
</series>

As you can see, you can set bg_color and bg_alpha attributes in data file.

I hope these two features will be useful.
