think-cell 5.3 – User Guide

See Formatting and style on page 24 for details on these
controls. Labels for the data points are not shown by default
but may be displayed using the line chart Add
Point Label context menu button.
If the category values of a line chart are strictly increasing
numbers or dates then the x-axis will automatically
switch to a value axis (see Value axis on page 40).
When dates are used the date format can be changed
by multi-selecting all category labels (see Multi-selection
on page 23) and typing a date format into the control
(see Date format codes on page 72). If you want to show
more labels than would fit next to each other horizontally
you can use label rotation (see Label rotation on
page 32).
The horizontal axis can only switch from category to
value mode if the following conditions are met:
– All category cells in the data sheet contain numbers
and Excel’s cell format is also set to General or Number
or all category cells in the data sheet contain dates
and Excel’s cell format is also set to Date.
– The numbers or dates in the category cells are strictly
increasing from left to right.
– The y-axis is not set to Crosses Between Categories (see
Positioning the value axis on page 41). If only this
requirement is preventing a switch to the value axis
mode, you can use Make Value Axis from the axis
context menu to switch to Crosses At Categories and
thereby switch to the value axis mode as well.
The line chart can also display a second vertical value
axis. Please refer to Secondary Axis on page 44 for further
information.
Smoothed lines
Column chart, line chart and area chart 38
If you prefer a smoother appearance of the lines in a
line chart, you can turn on this setting. First right-click
on the desired line, then use the Set to Smooth Line
button.
Error bars
Error bars can be used to indicate deviations. By means
of the error bars the following chart can be created.
1. Create a line chart with three series. The first series
reflects the upper deviation, the second series reflects
the mean and the third series reflects the lower
deviation.
2. Right-click the center line and choose Add Error
Bars from the context menu.
3. Remove the series labels for the upper and lower
series.
Select one of the error bars to change the marker shape
and color for the upper and lower deviation and the line
type of the bar for all error bars. You can also select an
individual error bar marker to change the properties for
this marker only.
