amCharts & amMap blog

Today version 1.3.0 of all charts was released. Here is a list of new features:

All charts:

1. More possibilities to control "export as image" feature: change position, background color and alpha, text color, target
2. export.php and export.aspx.cs files where improved (opens "save as" window)
3. More possibilities to control error messages: change colors, position, disable error messages

Line, Column and Bubble charts:

1. a possibility to have reversed axis values
2. value indicator plug-in
3. if there are non-integer axis values, zeroes are added to those values which has less numbers after comma (this gives x axis values a better look and readability)
4. strict min & max added for column and bubble chart
5. a possibility to exclude certain graph  from the legend
6. two more build-in bullets: round_outlined and square_outlined

Pie chart:

1. values can be displayed in the legend

All charts are backward compatible, however if you’d like to use new features, you should update some of your settings. Pie chart is not compatible with versions less then 1.1

A more detailed description of new features is coming

In a new version of line chart (1.2.13) you can display values near your points. The settings are the same as column chart’s:

<graph id="0">
  ……
<data_labels>{value}</data_labels>
<data_labels_text_size>10</data_labels_text_size>
<data_labels_text_color>#CC0000</data_labels_text_color>
<data_labels_position>above</data_labels_position>

You can format any data label, do not forget <![CDATA[]]> if you use HTML tags.

You can display data label above or below your points.

To avoid overlapping, data labels, the same as bullets, are hided if you have more series then specified in:

<hide_bullets_count>10</hide_bullets_count>

This would mean that if you have 20 series data labels will not be visible. And if you select (zoom) range with 10 or less series, the labels will be displayed.

Here is an example. Try to select short period (<10 series) and you will see data labels near "anomaly" graph.

If you want to display only some of data labels, you can use description for it. Set description for your value (you can do it only if you are using XML data file):

<value xid="10" description="50">50</value>

And then set that you want to have description in your data labels:

<data_labels>{description}</data_labels>

Update:

you can set individual data label position in data xml file:

<value xid="1" label_position="below">44</value>
