In addition to zooming (see Zooming a Section of a Chart), you can also adjust the vertical and horizontal scaling of a chart.

Vertical scaling

You can set the vertical scaling to dynamically adapt to the section of the time series that is shown on the screen, or to relate to the fixed maximum and minimum points of the loaded historic data. You can also move the time series freely on the screen by dragging it up or down.

To vertically scale the time series to the screen

▪       Click on the Adjust Screen Mode icon  on the Chart toolbar to toggle between the two following settings:

Scale visible time series

Only the part of the time series that is visible on the screen is taken into account for vertical scaling. When you scroll the chart to the left or right with the scrollbar, the scaling is adjusted dynamically so that the maximum of the visible time series is always at the top of the chart, and the minimum of the visible time series is at the bottom of the chart.

This is the default setting.

Scale entire time series

The entire loaded time series is taken into account for vertical scaling, including historic data that might not be visible at the moment. When you scroll the chart to the left or right with the scrollbar, the scaling does not change, as the size of the vertical scale has been determined already by using the maximum and minimum of the entire time series.

This setting might lead to blank spaces at the top or bottom of the visible part of the chart, especially when you load a lot of historic data to your chart.

Note             For more information about the vertical scaling of a chart, see Changing the Scaling of the Price Scale.

To move the time series on the screen with drag and drop

▪       Click on the Free Hand icon on the Drawing toolbar:

▪       The mouse pointer changes:

▪       Click on the chart, hold the mouse button down and drag the chart into any direction. The time series is positioned on the screen accordingly.

Note             The Free Hand tool will stay active as long as you do not use another tool. To deactivate it, click on another tool icon, or press the Esc key on your keyboard. When you save a chart while the Free Hand tool is active, this setting will be saved as well.

Horizontal scaling

You can adjust the horizontal scaling by expanding or compressing the time series (similar to zooming), or by adjusting the scale so that all available data is shown on the screen at once.

To expand the time series (show less data points on the screen)

▪       Click on the Expand icon on the Chart toolbar:

Note             You can also press the – Minus key or Del key (when no chart object is selected).
This function is similar to the Zoom In tool. See Zooming a Section of a Chart.

To compress the time series (show more data points on the screen)

▪       Click on the Compress icon on the Chart toolbar:

Note             You can also press the + Plus key or Ins key.
This function is similar to the Zoom Out tool. See Zooming a Section of a Chart.

To show the entire data series on the screen

▪       Click on the Show All Data icon on the Chart toolbar:

Note             You can also click the Data View button  and choose Show all data instead.

Chart reset

When you have zoomed into the chart, set custom scaling options or pane margins, you can always return the chart to its default state. Other settings (chart type, data compression, colors etc.) will not be affected by this.

To reset the chart to its defaults (zooming, scaling and margins)

▪       Click the Data View button  and choose Chart reset.

Note             You can also press the Home key to reset the chart.
