candlestick-chart

I am using geom_boxplot to draw candlesticks using stock market data. The problem is that the individual boxplot's upper and lower edges as well as the upper whisker end point show up way higher on the y-axis than their corresponding values. The relative height (difference between upper and lower edges) and the end point of the lower whisker of each boxplot are fine though. Here's my code : candlestickPlot <- function(x){ library("ggplot2") # x is a data.frame with columns 'date','open','high','low','close' x$candleLower <- pmin(x$open, x$close) x$candleUpper <- pmax(x$open, x$close) x

I was looking for a candlestick lib chart solution for android, and couldnt find one for a couple of months now. Im looking for a smooth scrolling, zomming, tooltip, option to polt in a new candle without the need to render the entire chart. i did come across all the normal options for native code charting: DriodCharts, AchartEngine, ChartDroid, none of which support candlesticks. I also used 5 free Javascript and html solutions, all of which are very very slow, and most dont support adding a data tick after the chart has been plotted. I have seen many free android applications with decent

I am trying to make a simple candlestick ohlc chart with mpl_finance. On their website, it says that the first element in the quotes argument of the candlestick_ohlc method is the dates. It says that they must be formatted in the float date format. When i use date2num however, it gives me an error that says"Cannot convert -100000 to a date. This often happens if non-datetime values are passed to an axis that expects datetime objects." When i use my original list without the date2num method, it gives me an error that points to a line of code- xy=(t-OFFFSET, lower) and a message -"unsupported

I am developing a candle chart in C #. I've been working on creating candle charts using data from the current datagridview. Additionally, when I place the cursor over the candle point of the chart, I want to show the information (open, close, high, low) of the datagridview. (See image) Currently developed source. DataTable table_ChartData = new DataTable(); table_ChartData.Columns.Add("Id"); table_ChartData.Columns.Add("Open"); table_ChartData.Columns.Add("Close"); table_ChartData.Columns.Add("High"); table_ChartData.Columns.Add("Low"); table_ChartData.Columns.Add("Day"); dataGridView1

I am trying to plot some financial candlestick charts with gnuplot. The problem is that there is no data during the weekends, and I don't want these gaps to be showed. Picture and code included below. set datafile separator "," set xdata time set timefmt"%Y-%m-%d" set xrange ["2015-10-22":"2016-02-06"] set yrange [*:*] set format x plot 'head.dat' using 1:2:4:3:5 notitle with candlesticks Joce As you have one entry per working day, instead of using the dates as abscissae you can use the line number: plot 'head.dat' using 0:2:4:3:5 notitle with candlesticks Then I guess you'll ask how to
