You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

More Improvement to Line Charts

You can now set lines in a line chart to either dotted, dashed or solid:

Line chart styles

An example of each of the 3 types of line style.

You can also control how the legend for lines charts appears.

However, this update seems to have removed the option to set line markers completely, as this forum agrees.  I'm sure this will be fixed by an update very soon ...

Changing Line Styles 

To do this, use the Shapes section of the Formatting toolbar

Line styles

You can set the line style for all lines in your chart, or (as here) toggle the Customize series option, then use the drop arrow to set different lines styles for different data series.


Changing Legend Appearance

You can (as mentioned) also control how line charts show legends:

Legend style

You can set the legend style to show just markers, just lines (as here) or both lines and markers.


For this choice (Line only), here's what you'd see for the above chart:

Line only legend

The legend displays just the line segment.


If you choose to show the legend as just a marker, you can either display this as a circle (the default) or as a line:

Circle default icon

Here we've turned the default circle icon off.


Without a circle icon, the legend appears as a solid line:

Legend as solid line

The legend using a solid line.


The Match line color property above determines whether the legend colour matches the colour of the line (On) or marker (Off).  As I mentioned at the top of this blog, this feature is a bit academic, as the option to set line markers seems to have been temporarily removed!
