View creating and linkage display

DataInsights supports visualizing spatial data on map, creating thematic maps, creating charts by one-click and supports mouse drag operations. Maps include Classic, Unique, Range, Symbol Size and Heatmap; charts include Histogram, Bar chat, Bar graph, Pie chart, Line chart, Tree chart, Radar chart, Word cloud, Scatter chart, Box chart, Heat chart and Relation graph. Text view and Image view are also supported.

Views can be repositioned and reordered by dragging and dropping, and each view size can be adjusted by dragging in eight directions. The added views can be downloaded as PNG individually, while the entire workbench can be exported as PNG or PDF. Additionally, multiple maps and charts created based on the same data are linked by default; all map views support view synchronously based on the center point.

Create maps

Three ways are supported for creating maps:

• On the Workbench page, move the mouse cursor over the field with which you want to create a map, and select icon to create.
• In the upper navigation bar, select "Add Views > Map >Create from data", select the field which you want to create a map, click the "OK" button to create.
• In the upper navigation bar, select "Add Views > Map > Choose from my map". You can choose a map from the "My Maps" list, then click the "OK" button to create.

Note 1: The map views can be created when the projection of the added data is EPSG Code: 4326, EPSG Code: 3857, EPSG Code:4490, or Baidu coordinates.

Note 2: Maps with projections EPSG Code: 4326, EPSG Code: 3857, and EPSG Code:4490 can be added to the "My Maps" list.

Toolbar and Map Controls

The selected Map View will display the title and a toolbar with "Lower", "Export", "Clear Highlight", "Maximize/Return", and "close" buttons. The specific functions are as follows:

• Lower: Place the map view at the bottom, and you can overlap other views onto it.
• Export: Export the current map view as a PNG image to local.
• Clear Highlight: If you have selected data in the map, you can clear the selection by clicking this button.
• Maximize/Return: Zoom in/zoom out the map view.
• Close: Delete the map view.

The left side of the map view lists controls, including zoom in, zoom out, reset bearing, maximize, and measure controls. The specific functions are as follows:

• Zoom In: Click to enlarge the map twofold, or use the mouse wheel to zoom in.
• Zoom Out: Click to shrink the map twofold, or use the mouse wheel to zoom out.
• Reset Bearing to North: Reset the orientation of the map view after pitching or rotating the map.
• Maximize: Display the map view in full width.
• Measure: Supports distance and area measurement.

Additionally, DataInsights provides in the right-hand panel of the editor to display the layers in the current map, and you can create different thematic maps based on each layer; , with analysis functions for data added to the map, see: Performing analysis; , to modify the map view title, add remarks, and change the basemap. Map views created by default will use the default basemap set in the toolbar "Settings > Map > Basemap". The detailed operations of are as follows:

• Adding a layer: supports adding data to the map. You can drag a data field from the Data panel on the left to the map view to add layers. Added layers will create thematic maps with the dragged data fields by default, and you can expand this layer on the right to adjust the thematic style.
• Adjusting the order of layers: you can adjust the order of layers by dragging them up and down.
• Remove layers: you can remove any layer except the basemap.
• Show/Hide layers: show or hide any layer except the basemap.

Types of thematic maps

Classic

Set a global style for all features in the layer based on the selected data field.  The point feature layer supports setting the color of the point symbol; the line feature layer supports setting the line style and color; the polygon feature layer supports setting the fill color.

Unique

Set a unique rendering style for each class of features with the same thematic value based on the selected data field, and you can distinguish features of different thematic values by their color.

Range

Range thematic maps require the selected field to be of the numeric type. In a range thematic map, the thematic values are divided into different segments according to the segment method. The features are assigned to one of the segments according to their thematic values and use the same style within the same range segment. A criterion for good segmentation is whether features with similar values are in the same segment. Two important factors determine the presence of a range thematic map: the segment method and the number of segments. The DataInsights supports the following segment methods:

• Offset Segment: Segment equally based on the maximum value, the minimum value of all thematic values and the number of segments specified. In Offset Segment, each segment length is equal.
• Natural Breaks: Segment based on the natural groupings within the data. The difference within the same range segment is the smallest, and the difference between different range segments is the largest. This segment method is based on Jenks Natural Breaks algorithm.
• Square Root Segment: Segment equally based the square root of the thematic value determined by the thematic field.It is suitable for the following situations:
• There are no negative numbers in the data.
• There are large differences between the maximum and minimum values of thematic values.
• The results are unsatisfactory when using Offset Segment.
• Logarithm Segment: Calculate the logarithm of the thematic values determined by the thematic field, then use Offset Segment based on it.It is suitable for the following situations:
• There are no negative numbers in the data.
• There are large differences between the maximum and minimum values of thematic values.
• The results are unsatisfactory when using Offset Segment and Square Root Segment.

Symbol Size

Symbol Size thematic map is similar to the range thematic map, except that each segment is represented by a dot symbol of a different size. DataInsights supports setting minimum radius, maximum radius, and fill color of the dot symbol. Only point features support this thematic map.

Heatmap

Heatmap shows the distribution of two-dimensional discrete data by color, and it can present the trend of decay of the weight value of each discrete point and the superposition of decay between discrete points. Heatmap needs to set the weight field, hotspot radius (in pixels), and color. Only point features support this thematic map.

Create charts

Similar to maps, creating charts supports two ways:

• On the Workbench page, move the mouse cursor over the field with which you want to create a chart, and select icon to create a chart.

• In the upper navigation bar, select "Add Views >Chart", select the field with which you want to create a chart, click the "OK" button to create.

Toolbar

The selected Chart View will display the title and a toolbar with "Export", "Clear Highlight", "Maximize/Return", and "Close" buttons. The specific functions are as follows.

• Title: The selected chart view will show the title which can be changed in the right-hand panel by clicking on the button , you can also add a remark to the chart view.
• Export: Export the current chart view as a PNG image to local.
• Clear Highlight: If you have selected data in the chart, you can clear the selection by clicking this button.
• Maximize/Return: Zoom in/zoom out the chart view.
• Close: Delete the chart view.

Additionally, DataInsights provides for switching chart types, setting chart parameters and styles; , for filtering the range of data in the chart; and , for modifying the chart basic information. The following are introductions of chart type:
