Time-Series Charts
Time-series Charts are the best way to visualize time-series data. They can render as lines, points or bars.
Single Time-Series
Multiple Time-Series
This is an example of a TAQ Chart.
Dual-Axis Time-Series Chart
On the right hand-side, the 1.axis 2.coloring 3.type 4.symbol can all be customized.
Smooth Line vs Step Plot
Chart Margin Spacing
On the right hand-side, under the collapsible basics options, the margin spacing can be configured to adjust spacing around the chart.
Chart Title and Legend
On the right hand-side, under the collapsible title/legend, the text for a chart title can be set as well as it's coloring and spacing.
Configuration
You can configure the appearance of a column by adding an _SD_FORMATTER at the end of the column name.
For example if a column was call itemPrice, you could name it itemPrice_SD_CIRCLE to show the chart without a line and instead showing circle markers. Additionally you could add a column named: itemPrice_SD_SIZE to set the size of the circle/symbol.
| Area | Example | Options | Description |
|---|---|---|---|
| Shape | _SD_CIRCLE | CIRCLE, RECT, ROUNDRECT, TRIANGLE, DIAMOND, PIN, ARROW, NONE | The shape to use for displaying points in the chart. |
| Shape Size | _SD_SIZE | Number 1-99 | The size of the shape to use for displaying points in the chart. You MUST have set an SD_SHAPE first. |
| Point Marker | _SD_MARKPOINT | String | Adds a labeled point to the chart at the corresponding point. |
| Point Line | _SD_MARKLINE | String | Adds a labeled vertical line to the chart at the x-axis/time location. |
| Point Line | _SD_MARKAREA | String | Adds a shaded area to the chart between when the label starts and finishes. |
See TAQ Chart for an example of using these configurations.
Markers
An example of markers is shown below. As you can see from the table, you add special _SD_ columns to generate the markers. The column MUST begin with the name of an existing column as the points and lines are associated with that column.
