JavaScript Data Visualization with SpreadJS Sparklines

  • Display trends in a minimal area using this alternative to standard charts
  • Visualize a group of data by placing a sparkline in a spreadsheet cell
  • Provide a graphical representation of your data using a variety of sparkline types


SpreadJS provides many options to improve data visualization – one option is sparklines. Sparklines provide a graphical representation of your data in a single cell. Embed these small charts into any cell to quickly show trends in your data, such as increases and decreases, minimum and maximum values, stock levels, costs, and more.

Easily Identify Data Trends with Sparklines

Horizontal Cascade

Show how transactions change between a starting and ending value with vertical or horizontal bars to display data and data values.
