Release Notes

Streamline Control is releasing version 1.1.1 of SC Charts. Updates from version 1.0.0 are described below.

Features

Chart Configuration
  • Append Mode

    • Add a data mode to append data from the dataset on every update to reduce the traffic over the Ignition websocket where required. Previously data from the dataset replaced all data on the chart; this functionality is maintained through the default Replace mode.

    • New data properties include: mode, capacity, clearCache,  currentCount; the last three only apply when the mode is ‘Append’.
  • Axes
    • Add default axis properties so not all properties need to be specified when adding an axis.
    • Add read-only currentMin and currentMax properties to axis range that are updated when the range changes as a result of panning or zooming or when the extents change due to auto-ranging.
Performance
  • Update pens and axes without creating new ones where possible.
    • New axes and pens are still created when the axis name or type changes, pen data, type or axis (if the overview exists) changes, data mode or capacity (in append mode while interaction.playPause.updateData is true) changes, interaction.playPause.updateData changes to true, or the overview axes change.
  • Store pen data and use it to rebuild the series if new axes or pens were created.
  • Improved context rendering for WASM backend in Firefox.

Fixes

  • Axes
    • Apply label format on DateTimeNumericAxis.
    • Do not write a console warning if min and max axis range are configured for a never auto-ranging axis.
    • Shift the x-axis if more than one point is added when zoomed on y-axis or zoomed on the x-axis with the last point visible.
    • Prevent Designer errors when datetime objects are used for axis range min or max properties.
  • Prevent undeleted objects if a new axis and pen are added at the same time when there is an overview.
  • Prevent errors if multiple pens have the same name.
  • Prevent Designer from crashing if logarithmic axis range min is <1e-100 by setting it to 0.001.
  • Allow number and string types for chart height.
  • Prevent errors in the Designer when invalid colors are entered.
Interactions
  • Prevent issues with size and placement of annotation and measurement info boxes by setting a minimum padding value of zero.
  • Prevent zoom from being reset when new data comes in while panning with mouse button down on the x- or y-axis.
  • Reset interaction.download.triggerDownload property after download is complete.
  • Interactions
    • Add color picker in Designer for dot stroke and fill properties.
    • Allow number and string types for overview height.
