I am on a mission to make a candlestick graph using MSChart in a windows form. I already succeeded to make a 3D bar chart with no problems. But after a long search on the internet, Microsoft's source code (WinSamples) and a lot of headscratching I can't find the right way to create a candlestick graph. What could help me is a clear example of adding a serie to the chart with multiple Y-values or a correction of my code (when i run, debug nothing shows up exept for the legend label). A bonus would be that the example is based on OleDB (my values are in an Access database). So my question: If

i'm trying to use Google Chart API for building an Waterfall chart. I noticed that Candlestick/Waterfall charts are not supporting the annotations. See this jsfiddle sample google.charts.load('current', {'packages':['corechart']}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Category'); data.addColumn('number', 'MinimumLevel'); data.addColumn('number', 'MinimumLevel1'); data.addColumn('number', 'MaximumLevel'); data.addColumn('number', 'MaximumLevel1'); data.addColumn({type: 'number', role:

阅读更多关于 matplotlib.finance.candlestick_ohlc plot intraday 1min bar data with time breaks and proper xticklabels at every hour

问题 The problem is: I want to plot the intraday 1 minute OHLC bars of one stock. The daily trading hour is composed of several segments of trading periods. Which is listed below: Trade date: 2017/09/14 Included trading hour: 2017/09/13 21:00 - 23:00, 2017/09/14 9:00 - 10:15, 10:30 - 11:30, 13:30 - 15:00. As you can see, if I just use candlestick_ohlc directly, there will be gaps. Now if I get 1minute data as a dataframe. How can I plot a candlestick graph, with no gaps between any bars(e.g, no

JFreechart candlestick chart weird behaviour on drag

This is a follow up question from this question .

Then when I drag further, they become thicker again until they are normal size again. This seems to happen for every 7 periods. An example of this phenomenon is displayed on to the following 3 pictures: The following code will show exactly what I mean. Just compile and run it. Then press and hold CTRL and click and

Has anybody come across this before? ps. as requested, here is the example: #!/usr/bin/env python from pylab import * from matplotlib.dates import DateFormatter, WeekdayLocator, HourLocator, \ DayLocator, MONDAY from
