For example, a variable could have a quadratic trend: Y t = a ⋅ t + c ⋅ t 2 + b + e t . {\displaystyle Y_{t}=a\cdot t+c\cdot t^{2}+b+e_{t}.} This can be regressed linearly in the coefficients using t and t 2 as regressors; again, if the residuals are shown to be stationary then they are the detrended values of Y t {\displaystyle Y_{t}} .
Trend-following indicators are technical tools that measure the direction and strength of trends in the chosen time frame. Some trend-following indicators are placed directly on the price panel ...
If a chart plots 10 colors or fewer, then by default it uses every other one: The colors can be manually set in a graph by adding them to the 'colors' parameter. For example, for two pie charts, the first of which is default and the second of which omits some colors in the first, you would manually enter your selections from the default 20:
Open-high-low-close chart – OHLC charts, also known as bar charts, plot the span between the high and low prices of a trading period as a vertical line segment at the trading time, and the open and close prices with horizontal tick marks on the range line, usually a tick to the left for the open price and a tick to the right for the closing ...

The X-bar chart is always used in conjunction with a variation chart such as the ¯ and R chart or ¯ and s chart. The R-chart shows sample ranges (difference between the largest and the smallest values in the sample), while the s-chart shows the samples' standard deviation. The R-chart was preferred in times when calculations were performed ...
The chart portion of the forest plot will be on the right hand side and will indicate the mean difference in effect between the test and control groups in the studies. A more precise rendering of the data shows up in number form in the text of each line, while a somewhat less precise graphic representation shows up in chart form on the right.
For example, the price of a share reaches a high of $30.00 on Wednesday, and opens at $31.20 on Thursday, falls down to $31.00 in the early hour, moves straight up again to $31.45, and no trading occurs in between $30.00 and $31.00 area. This no-trading zone appears on the chart as a gap.
