Chapter 3 The Tariscope program
3.7 View for charts
The reports discussed in Section 3.6 can contain both text and graphical information. At the same time, the Tariscope program has a separate Chart function that allows you to quickly create a chart based on the data of views for calls.
Consider creating a chart based on the following example. We wish to know the distribution of the costs of all subscribers on long-distance calls.
We open a view for calls. Using the filtering we select only long-distance calls.
Since we are interested in the distribution of costs of all subscribers, we hide all columns of the view except the To destination and Cost columns. Then we group information by the To destination field. We sort the data by the Cost column. The view will be as shown in Figure 3.7.1.
Figure 3.7.1
Since we are interested in the basic costs on calls, we select only first ten cells in the Cost column. Then we select in the program menu: Data → New chart or we can click on the Chart icon on the toolbar. The Chart settings window appears as shown in Figure 3.7.2.

The Style list allows you to select a desired style from the following options:
- Area;
- Histogram;
- Line;
- Pie.
In the Name box, the user can change a chart name that is offered by default.
The Data range box displays the selected cells of the table. You can change the range. To do this, click on the '...' button located on the right from the box. The Select range window appears where you should select a desired cell range.
The Legend in first column list displays the column name, which is used as a legend in the chart. You can change a default value.
The Series in row and Series in column check boxes allows setting a type of displaying the legend.
We select the Pie style for our example and get the chart as shown in Figure 3.7.3.

A view for charts allows to save the chart as a picture. To do this, click on the Save as icon on the toolbar of the view.
Also you can print a chart. To do this, click on the Print icon on the toolbar of the view.
