​
Setting a style

Pass a style string in the options object at the top-level declaration: 
plot("Hist", null, { style: "histogram", color: "#a78bfaFF" });

​
All 12 styles

​
line (default)

Continuous line connecting each bar’s value. 
plot("SMA", null, { style: "line", color: "#22c55eFF", linewidth: 2 });

​
stepline

Horizontal segment to next bar, then vertical jump. Classic staircase. 
plot("Step", null, { style: "stepline", color: "#f59e0bFF" });

​
stepline_diamond

Step line with diamond markers at each vertex. 
plot("StepDiamond", null, { style: "stepline_diamond", color: "#a78bfaFF" });

​
histogram

Vertical bars from 0 to the value. Positive values grow up, negative values grow down. 
plot("MACD Hist", null, { style: "histogram", color: "#22c55e80" });

​
columns

Alias for histogram. Identical rendering. 
plot("Strength", null, { style: "columns", color: "#3b82f680" });

​
area

Filled area between the line and 0 (clamped at zero). 
plot("Volume area", null, { style: "area", color: "#22c55e40" });

​
areabr

Area on baseline - not clamped to 0; fills between the value and the chart baseline. 
plot("ATR band", null, { style: "areabr", color: "#ef444430" });

​
linebr

Line on baseline. Similar to areabr but no fill. 
plot("Linebr", null, { style: "linebr", color: "#6b7280FF" });

​
circles

Discrete dots at each bar’s value. No connecting line. 
plot("RSI dots", null, { style: "circles", color: "#f59e0bFF" });

​
cross

Cross marker (+) at each bar’s value. No connecting line. 
plot("Pivot", null, { style: "cross", color: "#a78bfaFF" });

​
arrowup

Arrow pointing up when value > 0, down when value < 0. Good for signal markers. 
plot("Buy sig", null, {
  style: "arrowup",
  colorUp: "#22c55eFF",
  colorDown: "#ef4444FF",
  size: 8,
});

​
arrowdown

Arrow pointing down when value > 0, up when value < 0. 
plot("Sell sig", null, {
  style: "arrowdown",
  colorUp: "#ef4444FF",
  colorDown: "#22c55eFF",
  size: 8,
});

onBar(() => {
  const rsi = ta.rsi(ctx.close, 14);
  const crossOb = ta.crossunder(ta.rsi(ctx.close, 14), 70);
  plot("Signal", crossOb ? 1 : NaN);
});

​
Histogram with per-bar color

For histograms where you want different colors for positive/negative values: 
plot("MACD Hist", null, {
  style: "histogram",
  colorUp: "#22c55e80",
  colorDown: "#ef444480",
  histbase: 0,
});
