Often a single graphical representation does not allow data to visualized in the ideal manner.
For example, Strip-Charts are excellent for comparing data values at a given point in time and
seeing how those values vary over time. They cannot however be used to display the correlation
between two variables and are not an ideal mechanism for deciding whether a large set of
parameters are remaining within a defined target range.
To address this, V3-0 of SapphireTrend provides four alternate graph styles:
- Strip Charts
A well established method of representing continuously varying values by plotting a series of data points against time.
- X-Y Scatter Graphs
An effective mechanism for looking for correlations between pairs of data points. As this representation is not time based it is possible to see patterns and relationships that cannot be seen via
strip-charts or radar plots.
- X-Y Line Graphs
Similar in nature to X-Y Scatter graphs, but instead of each data pair being delimited
by a symbol, consecutive data pairs are connected with lines. This provides some time sequencing which is not possible
with X-Y Scatter graphs.

- Radar Plots
A convenient mechanism for monitoring a large number of items simultaneously whilst tracking whether the overall process is within specified target ranges. By checking for deviations from an expected
outline users can quickly identify when a production process is drifting out of specification or recognize when
desired targets are no longer being met.
- Stacked Strip Charts
Similar in concept to Strip Charts, Stacked Strip Charts differ in that each pen is
given it's own plot region within the Plot window. Stacked Strip charts should be used when maximum clarity is required as by
implication none of the trend lines will overlap.
