Px-simple-line-chart is a Predix UI component used to visualize a series of numeric values as a line chart. The series is represented by a thin blue line connecting a sequence of points, the position of each proportionally point representing a single coordinate value.
Optionally, a threshold value may be defined to draw a thin orange line horizontally at the y-axis point representing the value. By default a threshold label will be drawn in an axis bar on the left side of the chart. If a custom threshold label is necessary a string may also be passed to the component as threshold-label.
In addition, a min and max may be configured in order to scope the chart to a specific range of y values. By default these will also be represented by labels in an axis bar on the left side of the chart. If custom labels are necessary they can be passed as strings to the component as min-label and max-label.
The width and height of the component are also configurable as well as the vertical columns and horizontal rows drawn in the background of the coordinate space.
We recommend viewing the demo page to see all the various configuration possibilities. We also recommend using the default settings as they are designed for proper performance.
