Basic Plotting Functions in Pine Script

Plotting functions are the backbone of visualizing data in Pine Script. They allow you to display indicators, price movements, and other relevant information directly on your charts. Here are some of the most commonly used plotting functions:

1. plot(): The plot() function is the most fundamental plotting function in Pine Script. It allows you to display a single series of data on the chart. For example, to plot the closing prices of a stock, you would use:

plot(close, title="Close Price", color=color.blue)

2. In this example, close refers to the closing price of the asset, and the title parameter sets the label for the plot on the chart. The color parameter specifies the color of the line.

3. plotshape(): This function is used to plot shapes on the chart, such as arrows or circles, at specific conditions. For instance, if you want to mark the points where the closing price is higher than the opening price, you could write:

plotshape(close > open, style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)

4. This code will display a small green triangle below each bar where the closing price exceeds the opening price.

5. plotbar(): The plotbar() function allows you to create custom bar charts. You can specify the open, high, low, and close values for each bar. For example:

plotbar(open, high, low, close, color=color.red)

6. This will plot red bars representing the price movements for the specified time frame.

7. hline(): The hline() function is used to draw horizontal lines on the chart at specified price levels. This can be useful for marking support and resistance levels. For example:

hline(50, "Support Level", color=color.red)

8. This line will draw a red horizontal line at the price level of 50, labeled "Support Level."

9. fill(): The fill() function allows you to fill the area between two plots with color. This can be particularly useful for visualizing ranges or bands. For example:

upperBand = sma(close, 20) + 1

lowerBand = sma(close, 20) - 1

plot(upperBand, color=color.green)

plot(lowerBand, color=color.red)

fill(upperBand, lowerBand, color=color.blue, transp=90)

10. In this example, the area between the upper and lower bands is filled with a semi-transparent blue color.
