Let us now see how to resolve this issue.

Open the table.
Right-click the Sales column and select Format Column.
In the Format Column dialog that appears, choose '2' from the drop-down that is available next to Decimal Places . This will limit the units after the decimal point to two.

Apart from decimal places, there are various other options that you can use to customize your data. Also, please do note that the formatting options in this dialog will change based on the data type of the column. Click here to learn more .
Click OK.

Now, this is how the report will look like.

Note: In case, if you have created a Pie chart, Zoho Analytics allows you to format the Percentage and Value datatype as shown in the image below.

Displaying Images in Chart

You can convert the URL text, in your chart labels, pointing to images to display the corresponding images.

Note : If you have formatted the URL data to display images in your data tables, the images will be directly displayed when you generate the chart using the URL column.

To render images from Image URL data types:

In the Chart Designer , drag and drop the Image URL column to the X-Axis, Y-Axis, or Color Shelf. The image support is currently available only for the columns dropped in these shelves. Here, we will add the Image URL column to the X-Axis.

Adding Threshold

Zoho Analytics provides you an option to draw threshold lines in a chart to highlight specific values. Threshold lines can be added horizontally or vertically at a fixed value on the X or Y-axis of a chart. A threshold will be useful to highlight specific values for better visualization and for comparing the data series.

For example, you can set a threshold line to represent maximum sale target, and another to represent the lowest acceptable sales target to spot regions that are out of sales target easily. Zoho Analytics allows you to add two types of threshold lines - Static and Dynamic Threshold lines.

  It is not applicable for charts with multiple columns in Y axis.
Select the reference axis from the Reference Axis drop-down.
Select Constant from the Value drop-down and enter a value.
Enter the desired name of the threshold line in the Name text box.

  Shown below is a sample screenshot displaying the threshold line based on the per cell. It displays the average sales per cell.
- Entire Table: Applies the same threshold for the entire table.
  
  Shown below is a sample screenshot displaying the threshold line for the entire table. It displays the average sales for the entire table.

Select the reference axis in the Reference Axis drop-down.
Select the function that you wish to apply from the Value drop-down. You can add dynamic functions such as Sum, Avg, Min, and Max on the reference axis column or on a different column.
