Though thee are many types of chart but most important types are as follows 
  1. Line chart
  2. Bar chart or OHLC chart
  3. Candle stick chart

Line chart


 It is the very basic chart which consists of only closing price under a particular time frame, here, like any other chart, time scale remain along the X axis and price scale stays with Y axis and closing price of a security under a particular time frame is plotted and then joined by a line to get a line chart



Bar chart or ohlc chart 

As the name suggests this kind of chart is made of bars contain Open. High. Low and Close price of a security, thus earning the name OHLC
In comparison with the line chart, which consists of closing price only, bar chart is far more informative which shows much more information at a glance


 

Japanese candlestick chart


Now ladies and gentlemen, please give a big hand as our darling Japanese candlestick chart is on the stage!!!!!!!!!!!!!
Like bar chart it is also derived form open /high/low/close of a security under a given time frame, like bar charts it is far more informative than its line counterpart, but it tells us more, various size of candles, individually and collectively plays a significant role and gives us very strong signals for future market action, candle color, candle size, size of its shadow, all are so much important to a trader that it can be used as all in all in the market. Though it’s mostly used along with some indicators to refine its results to even finer degree.
I know at first it will as tough as Hebrew to understand but once we master this charting system, we will be in a much safer water
