Bar Chart Static Series

With horizontal and vertical Bar Charts, you can set a series to be static (non-draggable).

To create this effect, we use two different series'. One of the series is the "hot" draggable series: it has its draggable property set to true, a snapping interval, and a hover cursor that indicates that the series is non-static (it indicates North-South or East-West movement). The other Series is the static series. Its draggable property is set to false. You can go even further by using a different hover cursor, removing the series from the Legend, disabling hover highlighting, etc.

An important attribute that makes this display properly for vertical and horizontal bar charts is the plotOptions --> column --> grouping --> false setting. Without this setting, the series columns will not align properly without extra settings.

Axis Title Formatting

The title of each axis can now be formatted. The font-weight and font-style for both the x-axis and y-axis can be specified based on the available options.

For font-weight there are 14 choices: normal | bold | bolder | lighter | 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 | inherit.
For font-style there are 4 choices: normal | italic | oblique | inherit.

Below are two axis examples with title formatting:
xAxis: { title: { text: 'X Axis Title', style: {'font-weight': 'normal', 'font-style': 'italic'} } yAxis: { title: { text: 'Y Axis Title', style: {'font-weight': 'bold', 'font-style': 'italic'} }

Point Labels

The labels for points can now be hidden on both the x-axis, y-axis or both.

Hiding the point labels is accomplished by adding labels: {enabled: false} to the appropriate axis.

Below is an example of an axis with labels hidden:
xAxis: { labels: { enabled: false } }

Descending Axes

Points on the x and/or y-axis can be configured to be in descending order. For example 10, 9, 8, 7, 6...

To have descending point labels, use reversed: true on the appropriate axis. In addition to reversing the axis, if you want the categories to start from a given value, you can define that thru the series low attribute.

Below is an example of a descending axis starting at 20:
{ xAxis: { reversed: true }, series: [ { data: [ { y:3, low:20 } ] } ] }

In the example to the right, the first and third columns are HOT, and the second and fourth columns are NOT.
