Minimum horizontal spacing, in pixels, allowed between two adjacent text labels. If false, will hide outermost labels rather than allow them to be cropped by the chart container.

I basically want to display a full candle chart at the beginning and the end of the graph instead of the existing half bar (Horizontally displays half of the candle bar). I have the option of tweaking my JSON data and add a fake amount, but prefer if I can manage this with existing options the charts.js might offer. Candlestick charts are often combined with line charts for showing different parameters in financial analysis. You can also combine Candlestick graph with spline, or area chart.
We shall use the setTickStrategy() function on an axis. This is used to set the tick strategy for the axis, as well as styling elements of the tick strategy. The second parameter is a mutator and is optional, only used when styling or modifying elements of the tick strategy. I am using Techan.js and d3 to display the charts, and Bootstrap for my CSS style. If set to true, allows the drawing of tooltips to flow outside of the bounds of the chart on all sides.
- You can also customize the color and thickness of line using lineColor and lineThickness.
- They can also be used to predict market reversals which can be extremely helpful for professional investors, brokers, etc.
- We don’t allow questions seeking recommendations for books, tools, software libraries, and more.
- Many traders consider candlestick charts to be easier to read and more visually appealing than conventional bar charts.

Lightningchart is one of the greatest libraries for easily creating candlestick charts. With Lightningchart JS, you can instantly plot price variations in the form of candlesticks. Candle Stick chart is a form of Column Chart which is used to represent price movements in a given time span. In Candle Stick Charts, Opening and Closing price forms the real body and a vertical Line (“Tail” or “Wick”) represents the High and Low values. When Closing Price is greater than Opening price, the body is filled with white by default and it can be overridden by risingColor property.
The default is true when focusTarget is set to ‘category’, otherwise the default is false. The color of the horizontal minor gridlines inside the chart area. The below snippet code is to generate some points using the ‘xydata’ library. The ‘xydata’ library provided by LightningChart, contains data generator functions that are used to generate sample data points in the form of x-data and y-data. This generator returns the object of OHLC data points.
Configuring the axis
You can enable legends by setting showInLegend to true. This feature is really useful for improving the readability of the graph. Other related customizations include exportEnabled, animationEnabled, etc.
- The default is true when focusTarget is set to ‘category’, otherwise the default is false.

In the resulting JS candlestick chart, it is possible to observe how the EUR/USD currency pair traded over two years. Use the scroller to zoom into a shorter period if you want. That’s where I will put all the code for the JS candlestick chart. When hovering the plot area, it helps to gauge a precise position on the value scale, helps display tooltips for multiple series at a time.
This candlestick chart is available right there so you can play with its code in a convenient way. After configuring the auto-cursor behavior and styling it, we get the output shown in the second image. The first image is showing to default cursor settings. As a stock price moves in one direction, individual candlesticks form various patterns which traders can use to identify and predict major support and resistance levels. Highcharts has a more full featured candlestick chart and the ability to reverse the y axis, but as far as I can tell you MUST use timestamps as values for the x axis.
