CARTO's Torque maps on Qlik

CartoQlik allows you to use CARTO's Torque map rendering library on Qlik Sense.

Features

• Static and animated maps, including heatmaps and category maps.
• Integrates with Qlik's data, and can also be used for data filtering.
• Easily change map layout, basemaps or animation parameters.
• Works nicely with even hundred thousand points.

Installation

Copy the project folder under <your HD unit>:\Users\<your user name>\Documents\Qlik\Sense\Extensions, you should now see the CARTO for Qlik extension on the charts tab.

Data

CARTO for Qlik works with 2 dimensions and 1 measure:

Dimensions

• Location: this is a GeoMakePoint string made from your latitude and longitude columns. This dimension is mandatory and must be the first one added to a map.
• Timestamp: this can either be an integer or a real timestamp.

This is an example of a typical data import script, when it comes down to defining these two dimensions:

Measure

CARTO for Qlik can make use of 1 measure, depending on the type of map.

• For a category map, this measure defines the data column that will be used to categorize the map. This measure shouldn't be aggregated.

• For any other map, this measure defines the data column and the aggregation function that will be used on the map.

Map configuration

Map options

• Map type:
  • Normal: Draws colored points based on location and, if defined, time and/or aggregation.
  • Categories: Draws colored points where each color represents a category based on the value of the column set as measure.
  • Heatmap: Heatmap based on point aggregation.
• Basemap:
  • Light: Our Positron basemap.
  • Dark: Our Dark matter basemap.

Map style

• Marker fill: Color of point fills.
• Marker width: Point diameter in pixels.
• Marker opacity: (0-1).
• Border color
• Border stroke: Border width.
• Border opacity: (0-1)
• Cumulative: Only for animated maps. If set, new points remain visible until the map loops.

Advanced options

• Category colors: Category are given random colors. However, it's possible to use a comma-separated list of colors from this field too. If there were more categories than items in this list, random colors would be used for the remaining.
• Animation duration: In seconds.
• Animation steps: Number of total frames for the animation. Typical values are: 256, 512 or 1024
• Initial zoom level, zero latitude and zero longitude: If set, the initial bounding box upon page reload will be taken from these values. If not set (or set to 0), the map will automatically fit its bounds.

Area filter

When the area filter switch is enabled, data that falls out of the bounding box of the map is filtered out.

carto-for-qlik's Issues

Investigate problems with big datasets and Qlik Sense 2.1

Extension seems to hang with big datasets (~500k points) and Qlik Sense 2.1.

Make config menu change based on current map type selection

It seems it can be done.

Category should be taken from a dimension, not a measure

Add autoplay and loop buttons

In map options menu

Area filter is broken in 2.1

Basemap disappears and filter is not created

Allow for a cartodb layer to be added to the map

Cannot use in desktop version

Check dimensions and measures instead of assuming they're in the right order

Qlikview support

Don't animate the map when in edit mode
