27 Charts in phpMyAdmin are drawn using `jqPlot <http://www.jqplot.com/>`_ jQuery library.
35 Query results for a simple pie chart can be generated with:
39 SELECT 'Food' AS 'expense',
40 1250 AS 'amount' UNION
41 SELECT 'Accommodation', 500 UNION
42 SELECT 'Travel', 720 UNION
45 And the result of this query is:
47 +---------------+--------+
49 +===============+========+
51 +---------------+--------+
52 | Accommodation | 500 |
53 +---------------+--------+
55 +---------------+--------+
57 +---------------+--------+
59 Choosing expense as the X-axis and amount in series:

66 Both bar charts and column chats support stacking. Upon selecting one of these types a checkbox is displayed to select stacking.
68 Query results for a simple bar or column chart can be generated with:
73 'ACADEMY DINOSAUR' AS 'title',
74 0.99 AS 'rental_rate',
75 20.99 AS 'replacement_cost' UNION
76 SELECT 'ACE GOLDFINGER', 4.99, 12.99 UNION
77 SELECT 'ADAPTATION HOLES', 2.99, 18.99 UNION
78 SELECT 'AFFAIR PREJUDICE', 2.99, 26.99 UNION
79 SELECT 'AFRICAN EGG', 2.99, 22.99
81 And the result of this query is:
83 +------------------+--------------+-------------------+
84 | title | rental_rate | replacement_cost |
85 +==================+==============+===================+
86 | ACADEMY DINOSAUR | 0.99 | 20.99 |
87 +------------------+--------------+-------------------+
88 | ACE GOLDFINGER | 4.99 | 12.99 |
89 +------------------+--------------+-------------------+
90 | ADAPTATION HOLES | 2.99 | 18.99 |
91 +------------------+--------------+-------------------+
92 | AFFAIR PREJUDICE | 2.99 | 26.99 |
93 +------------------+--------------+-------------------+
94 | AFRICAN EGG | 2.99 | 22.99 |
95 +------------------+--------------+-------------------+
97 Choosing title as the X-axis and rental_rate and replacement_cost as series:

104 Scatter charts are useful in identifying the movement of one or more variable(s) compared to another variable.
106 Using the same data set from bar and column charts section and choosing replacement_cost as the X-axis and rental_rate in series:

110 Line, spline and timeline charts
111 ++++++++++++++++++++++++++++++++
113 These charts can be used to illustrate trends in underlying data. Spline charts draw smooth lines while timeline charts draw X-axis taking the distances between the dates/time into consideration.
115 Query results for a simple line, spline or timeline chart can be generated with:
117 .. code-block:: mysql
120 DATE('2006-01-08') AS 'date',
123 SELECT DATE('2006-01-09'), 1898, 2301 UNION
124 SELECT DATE('2006-01-15'), 1560, 600 UNION
125 SELECT DATE('2006-01-17'), 3457, 1565
127 And the result of this query is:
129 +------------+---------+------+
130 | date | revenue | cost |
131 +============+=========+======+
132 | 2016-01-08 | 2056 | 1378 |
133 +------------+---------+------+
134 | 2006-01-09 | 1898 | 2301 |
135 +------------+---------+------+
136 | 2006-01-15 | 1560 | 600 |
137 +------------+---------+------+
138 | 2006-01-17 | 3457 | 1565 |
139 +------------+---------+------+
