ODM: Changing the bar chart format in Explore Node

Posted on

In Oracle Data Miner you can use the Explore Node to gather an initial set of statistics for your dataset. As part of this you will also get a bar chart that shows the distributions of the values contained within each attribute. The following example shows the default layout of the bar charts. Explore1

These graphs a very useful for presenting the initial data exploration results from to your business users. In addition to these graphs you can also use the Graph node to give some additional graphical representations.

But the default bar chart that is produced by the Explore Node can appear to be a bit basic.

So what if we could change the layout to have a 3-D effect. People like 3-D bar charts.

Is this possible in Oracle Data Miner? If so then how can we do it?

Well it is possible and you can use the following steps to change your bar charts to 3-D.

To access the Explore Node settings go the the Tools menu and then select Preferences from the drop down menu.

Then the Preferences window opens scroll down to the Data Miner option and expand the available options.

The Explorer Data Viewer allows you to change the Precision settings. The section option is the Graphical Settings. You can change the Depth Radius setting. By default this is set to Zero. By increasing this value you can change the degree of the 3-D effect of the bar charts. You can also change the colour scheme too.

I’m not a fan of the other colour schemes that are available and mu favourite is still the default Nautical. The following bar chart is the same as the one at the top of this post but has the 3-D effect.
