Chart Display

The Chart display interface is used to interact with the plotter area of the graphic. It is possible to highlight data of interest, zoom in, zoom out and pan over the plotter area. The basic appearance of the interface is explained bellow:


Graphic Style button - Opens up the chart style dialog which allows to change the style of the other items

Title - Chat title

Y Axis label

X Axis label

Plot area - The area where the chart is plotted.

The following steps will explain how to highlight objects over the plot area.



Highlight

The highlight function allows the user to highlight data of particular interest. The way to highlight the data will depend on the type of chart being shown on the display.



Histogram Highlight

To highlight a histogram interval simply click on the desired interval and all data contained in it will be highlighted on the chart and any other interface showing related data.

For example, clicking on the one bar will highlight the histogram bar and also the corresponding objects at the map display and at the table.


It is also possible to highlight more intervals once one has already been highlighted. In this case, the newly selected interval will be added to the previous. To do that hold the Ctrl or Shift button while clicking on the interval of choice.

It worth mention that the highlight can also start from the map display or table. Thus, if some objects are selected over the map display, the same objects will be highlighted over the histogram and table.



Scatter Highlight

To highlight a scatter interval click and drag the mouse button over the scatter plot area and a rectangle will be drawn, adjust its size to contain all the points of interest and all data contained in it will be highlighted on the chart and any other interface displaying data related to it (such as the map display or table).



It is also possible to highlight more intervals once one has already been highlighted, in this case, the newly selected interval will be added to the previous selection.To do that hold the Ctrl or Shift button while drawing the new rectangle of choice.

In any chart type, clicking on an empty space over the plot area removes all selected objects.



Zoom

Zooming in on a chart can be useful when the data being displayed contains to many intervals or points. In order to zoom in, roll the middle mouse button forward. To zoom out, roll the middle mouse button backwards.



Pan

It is also possible to pan the chart Display to check the data of a specific point that is out of the visible area (for example after a zoom). To do that, simply hold the middle button and drag the mouse to the desired spot on the display.
